Rory has a recipe for chocolate cupcakes. She uses 4 1/2 cups of flour to make 12 cupcakes. Camryn will follow the same recipe. She will make c cupcakes using f cups of flour. Which of these equations represents the relationship between c and f?
A. C = 8/3 f
B. c = ⅘ f
C. C = ⅜ f
D. C = 5/4 f

Step-by-step explanation:

First, divide the 12 cupcakes by 4 1/2. This will find the rate of change or slope of the equation. The answer of 12 divided by 4 1/2 is 8/3. That would make A the correct choice for this problem.

answer: c

because if you look at the chart you can see a pattern and compare it to the question he simplify out your

but i think the formula is f(x)=6x

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5
