-Part to Part to Part ratios compare 3 different groups from the same total to eachother.

Yellow to Red to Green

Choose a ratio to do in a Ratio form, Percent, Fraction, and Decimal.

Yellow to Red

6:10

Yellow/Red = 6/10

6/10= 0.6

0.6 x 100 = 60.0%


Make an Equivalent Ratio

I am going to use the one I just used.
Yellow to Red
6:10 = 3:5

6/2 = 3
10/2 = 5


Three Questions for you to do.
1) What is the Red to Total in an equivalent ratio?

2) Make a Part to Part to Part ordering the colours of M&M's from least to greatest.

3) How many Part to Part ratios could you make if there were two more colours there?



This is my BOB scribepost.
Please comment.





BOB Continued

I made mistakes by not looking my work over and by not going back to questions that I didn't get.
I can fix that on future tests by going back to do the hard questions later and reading the questions very slowly.

Warren stopped 90% of all the shots. There were 30 shots attempted. How many shots made it in?
A picture frame has a Width to Length ratio of 6:8. If the Width of the photo is 10 what is the Length?



Please answer my questions for my BOB PART 2
