Question

Sara baked chocolate chip cookies and oatmeal cookies. The ratio of chocolate chip cookies to oatmeal cookies is 3:2. If she baked 60 cookies, how many of each type of cookie did she bake?

Answer 1

Answer:

36 chocolate chip cookies and 24 oatmeal cookies.

Step-by-step explanation:

We have been given that the ratio of chocolate chip cookies to oatmeal cookies is 3:2. We are asked to find the number of each type of cookies.

We will use proportions to solve our given problem.

$\frac{\text{Chocolate chip}}{\text{Oatmeal cookies}}=\frac{3}{2}$

$\frac{\text{Chocolate chip}}{\text{Total cookies}}=\frac{3}{2+3}$

$\frac{\text{Chocolate chip}}{\text{Total cookies}}=\frac{3}{5}$

$\frac{\text{Chocolate chip}}{60}=\frac{3}{5}$

$\frac{\text{Chocolate chip}}{60}*60=\frac{3}{5}*60$

$\text{Chocolate chip}=3*12$

$\text{Chocolate chip}=36$

$\text{Oatmeal cookies}=60-36$

$\text{Oatmeal cookies}=24$

Therefore, Sara baked 36 chocolate chip cookies and 24 oatmeal cookies.
