Question

Your dog eats 7/8 lb of food in 4 meals , how many meals will it take your dog to eat 1 lb of food

Answer 1

x = 32/7, or 4 4/7 meals

Explanation:

Write and solve an equation of ratios, as follows:

7/8 lb 4 meals

------------ -------------

1 lb x

x will be the number of meals necessary for the dog to eat 1 lb of food.

Cross-multiplying, (7/8)x = 4.

Multiplying both sides by 8/7 is an easy way to isolate x:

(8/7)(7/8)x = (8/7)(4)

or

x = 32/7, or 4 4/7 meals
