Answer 1

1/10 acres

Explanation:

A land developer wants to divide up 9/10 of an acre Of land into equally sized lots for houses. He wants to build nine houses. How big can he make each lot?

This is calculated as:

1 lot = 1 house

Hence:

9 house = 9/10 acres

1 house = x

Cross Multiply

9x = 9/10 acres

x = 9/10 ÷ 9

x = 9/10 × 1/9

x = 1/10 acres

Hence, the size of each lot when divided equally = 1/10 acres
