Question

Naomi has earned $54 mowing lawns the past two days. she worked 2 1/2 hours yesterday and 4 1/4 hours today. if Naomi is paid the same amount for every hour she works, how much does she earn per hour the mow lawns?

Answer 1

2 1/2 + 4 1/4 = 6 3/4

6 3/4 = 27/4

$54\div \frac{27}{4} = 54\times \frac{4}{27} = 2 \times 4 = 8$

So Naomi earned $8 per hour that she mows the lawn.
