How to make equivalent fractions.

Equivalent fractions are just equal fractions. So to make an equivalent fractions, what ever you do to one side, you just have to do to the other side.

What is the ratio for purple to pink to silver ?

What would be the fraction from orange to silver?

What is the percent for purple to total?

Sorry if it's late .... I made one like a long time ago but for some reason I can't find it and I realized I had to make one so yeah ... sorry if it's real late.

Elona's BOB for October 29, 2009

MISTAKES

My first mistake is not showing my work.
My second mistake is not understanding the questions properly.
My third mistake is little studying.

QUESTIONS THAT WERE DIFFICULT FOR ME

In a group of 84 students surveyed, the ratio of student preference is 7 oatmeal eaters to 4 granola eaters to 3 toasted O eaters. Of the 84 students, how many prefer oatmeal and how many preferred granola?

Use the data in the table below to determine which sports teams have equivalent scored by to scored against ratios.

Team. Scored By Scored Against
Baseball Team A 10 8
Basketball Team A 115 92
Hocley Team A 6 4

WHAT TO DO IN THE FUTURE TEST
Study.
Show my work
Study.

BOB2
A normal deck of playing cards has 52 cards in four suits. (clubs, diamonds, hearts and spades.) of 13 cards each. Two of the suits are black, and two of the suits are red. The ratio of the red cards to the whole deck are:

R/TOTAL = 26/52
R/T = 2/4
answer: 1/2.

Kathleen's BOB

- 3 things I now know about graphing :

A (BAR) GRAPH needs to have the following :

• a title
  
• x and y axis
• scale * intervals must be same amount going up *
  
• labels for both axis
• colours are optional .

- advantages for different graphs :

Bar Graphs - are best for comparing data.

Circle Graph - are best for comparing categories when using percents.

Pictograph - are best for comparing categories that can easily be counted using symbols.

Line Graph - are best for showing changes of data over time.

Double Bar Graph - are best for comparing two sets of data.


- misrepresenting the data :

• Distorting a bar graph - making other bars looks different form the others makes you focus on that bar .
• Colours - if you change a colour of a bar , it makes the other bars looks like it is not important.
• Breaks - shorten the y-axis' appearance

Equivalent fractions are just equal fractions. So to make an equivalent fractions, whatever you do to one side, you just have to do to the other side.

For example, this picture shows the number of green Dots, to the number of total Dots. So to get an equivalent fraction, i just multiplied both the green and total by 2. You may also divide the two different numbers if you like. 

Here are 3 questions you guys could answer:

What is the ratio for mixed colored crayons to total crayons?

What would the percent be, for blue crayons to green crayons?

What would the decimal be, for pink crayons to total crayons?

My 3 Questions :

What is the ratio for blue to pink to total ?

What could the fraction 1/2 represent in this picture ?

What could the ratio 2 : 1 represent ?

Part 2:

3. A normal deck of playing cards has 52 cards in four suits (clubs, diamonds, hearts, spades) of 13 cards each. Two of the suits are black and two of the suits are red. The ratio of red cards to the whole deck is ...

mistake : 2:4

right answer : 1:2

5. Erci is able to stop 85 % of the shots on goal. If he faces 27 shots on goal, how many goals would likely be scored on him ?

mistake : 15

right answer : 4

In a group of 84 students surveyed, the ratio of student preference is seven oatmeal eaters to four granola eaters to three toasted 0 eaters.

14. What percent (to one decimalplace) of the group prefers toasted 0's ?

mistake : 18.7 %

right answer : 21.1 %

16. You have a bag with one white ball, six red balls, eight green balls, and three purple balls. In lowest terms, what is the ratio of red balls to the whole bag of balls ?

mistake : 6/8 = 1/3

right answer : 6/8 = 1/3 red balls : whole bag of balls

In the future I should read the questions clearly so that I'll see that I need the answers to be in lowest terms.

Next time I should pay attention to my ratio table so that I won't make any mistakes on my answers.

Next time when I'm trying to find a percent i should double check my ratio table to see if its correct.

2 Questions :

Alex is able to stop 65 % of the shots on goal. If he faces 36 shots on goal, how many goals would likely be scored on him ?

In a group of 75 students surveyed, the ratio of student preference is five oatmeal eaters to eight granola eaters to two toasted 0 eaters.

What percent (to one decimal place) of the group prefers toasted 0's ?

WRITING THE RATIO IN 4 DIFFERENT WAYS : ( fraction, percent, decimal ratio notation )

The ratio I chose is 1 : 2


FRACTION :

The way you write it in a fraction is that you just put the 1 on the numerator and the 2 on the denominator.

DECIMAL :

All you have to do is divide 1 to 2. So all the line means is to divide the numerator from the denominator. 1 / 2 = 0.5



PERCENTAGE :

To find the percentage you just need to use the decimal form. In this case, the decimal is 0.5. In other words that is 50 so there is your answer. 50 %

RATIO NOTATION :

All ratio notation means is the colon in the ratio. 1 : 2 . The colon between the 1 and 2 is ratio notation.


EQUIVILANT RATIOS :

I will choose the ratio 2 : 22 for this question.


Equivilant ratios for 2 : 22 :

- 1 : 11 ( ÷ 2 )
- 4 : 44 ( x 2 )
- 8 : 88 ( x 4 )

Thats how you simplify 2 : 22 in diffrent ways.


MY QUESTIONS :

1. Why do we use ratios? Explain

2. What is the part to part to part ratio for pink to orange to black ?

3. How do ratios help us in real life?

How to make equivalent ratios

Equivalent ratios are the same as fractions written sideways. It's written differently but means the same thing. For example, 2 : 4 is the same as 2 : 4. Whatever you do on one side, you do it on the other side.

Questions

1. True or False. A part to part ratio compares one part of a group to the whole group.

2. simplify 148 : 111.

3. If there are 3 stars and 1 moon. What should I write if I'm comparing moon to stars?Explain why.

The Ratio I choose is Blue to Yellow :

Ratio Notation - Blue to Yellow is 3:4

Fraction - 3/4

Decimal - 0.75

Percent - 75%

How to make an equivalent Fraction :

Equivalent fraction is like another word for equal fractions. In my diagram here it shows that the original fraction the numerator is 3 and I multiplyed it by 2 to get 6, so whatever you do to the numerator you HAVE to do the same to the denomenator so I multiplyed the denomenator and I got 8 because the original was 4.

PROBLEMS !! :

1) What would the decimal, Fraction and percent be for yellow to blue ratio ?

2) What would the Orange to White to Black ratio be ?

3) Write the ratio for Orange to total then write it in lowest terms.

Some mistakes I got wrong on MY test were :

1) I forgot to write the answer in the lowest terms.

2) I didnt show my work.

3) I didnt get the write percentage.

Examples and my mistakes :

1) For question 3 I put D which was 2:4 which was wrong because I didnt do it in lowest terms, the answer was B 1:2.

2) For questions 17 and 18 I just wrote down the answer, I didnt show my work like how I got the answers.

3) For question 14 the way i got the percent was totally wrong the right way was alot more different.

How I can remember in Future Tests :

1) I can remember writing in the lowest terms by reasding the question more carefully.

2) I can remember showing my work by instead of doing my work on a scarp piece of paper I can just do it on my test paper.

3)For getting the percent I would use a ratio table to get the correct percent.

Problems :

1) In a student election Carol gets 40% of the votes. If there were 525 votes cast, how many votes did Carol get ?

2) 5 students were running for student council president. Of 100 students polled, 50 chose mike, 9 chose Patricia, 24 chose Brian, and the rest chose Karen. What is the ratio of votes for boys to girls in the student council election ? Express the raio in lowest terms.
