http://www.flickr.com/photos/dmal/29775480134/

Part to part:

Peach to Orange -
1 : 2

Green to Light green - 1 : 1

White to Blue - 1 : 4

Part to WHOLE:

Yellow to total - 2 : 22

Blue to total -
4 - 22

Part to part to part :

Orange to blue to pink - 2 : 4 : 2

Peach to black to white -
1 : 1 : 1

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?

1. We use ratios to make comparisons between 2 things.

2. The part to part to part ratio for p:o:b is 2:2:1

3. We use ratios in real life to decide things. For example there is a 8:10 chance that it will snow tomorrow. That means it is most likely to snow. 80%.

1. Why do we use ratios? Explain

We use ratios to compare parts of groups together. Like if there is a group of numbers. 11 222 33 44444 555 how many 5's to 4's.

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

pink:orange: black

2 : 2 : 1

3. How do ratios help us in real life?

We use ratios , to determine the chances of things, happening..
