Question

zara baked 66 cookies for a class party. she made 4 sugar cookies for every 7 chocolate cookies. what was the total number of chocolate cookies that zara baked for the class party?

Explanation:

Step1: Find the total parts in the ratio

The ratio of sugar cookies to chocolate cookies is \( 4:7 \). So the total number of parts is \( 4 + 7 = 11 \) parts.

Step2: Find the value of one part

Zara baked a total of 66 cookies. To find the value of one part, we divide the total number of cookies by the total number of parts. So, \( \frac{66}{11} = 6 \).

Step3: Find the number of chocolate cookies

Since the number of chocolate cookies is 7 parts, we multiply the value of one part by 7. So, \( 6\times7 = 42 \).

Answer:

42
