The number of kilograms that an object weighs varies directly as the number of pounds. If an object weighs 45 kilograms or about 100 pounds, about how many kilograms is an object that weighs 70 pounds?

Answer:

This is the specific answer: 31.7515

Answer: 31.5

Step-by-step explanation:

To solve this ratio problem, you need the common ratio. Divide the amount of pounds by the amount of kilograms.

Step 1: Divide 100 pounds by 45 kilograms

100 ÷ 45 = 2.2

This is the common ratio

Step 2: Divide 70 pounds by 2.2

70 ÷ 2.2 = 31.5

This is the amount of kilograms in a 70 pound object
