Jose's BOB.Ratio for October 20, 2009



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%.
