Question

6. My dog GiGi eats 4.3 cups of dog food every 2 days. How many days can GiGi eat if only have 86 cups dog food left ?

Answer 1

40 days

Explanation:

Use a proportion.

4.3 is to 2 as 86 is to x

4.3/2 = 86/x

4.3x = 2 * 86

Divide both sides by 4.3

x = 2 * 20

x = 40

Answer: 40 days
