Question

A forest is decreasing in size by 150 hectares every 2 years . In how many years will the forest have decreased by 900 hectares ?

Answer 1

The forest would have lost 900 hectares in 12 years.

Explanation:

1. We want to find how many 2-year periods it will take to lose 900 hectares, so we divide 900 by 150.

2 When we divide 900 by 150, we find out 6, 2-year periods are required to lose 900 hectares.

3. Finally, then we multiply 6 and 2, which means it takes twelve years to for the forest to decrease by 900 hectares.
