Cheryl volunteers to mow the lawn at a retirement home. she can mow 1/4 of the lawn in 3/4 of an hour .at what rate ,how many hours will it take cheryl to mow the entire lawn

It will take three hours to mow the grass.

Hey there!

Since she mows 1/4 in 3/4 hours, you can multiply 4 and 3/4 . . .

4 = 4/1

3/4 = 3/4

4 x 3 = 12

1 x 4 = 4

Simplifying 12/4 . . .

12/4 = 3  <

It will take 3 hours for Cheryl to mow the entire lawn.

Hope this helps you.
Have a great day!
