PLEASE HELP I NEED SOMEONE ASAP
Michael and his sister Mel share the job of mowing the grass in their yard. Michael mows ⅓ of the yard, and Mel mows the rest. Mel can mow ¾ of the entire yard in an hour.
How long will it take Mel to finish mowing her part of the yard?

Respuesta :

Answer:

8/9 hours

Step-by-step explanation:

We need to determine how much of the lawn Mel has to mow

1 lawn - 1/3 of the lawn = 3/3 - 1/3 = 2/3

We can use a ratio to solve

3/4 lawn        2/3 lawn

-------------- = ------------

1 hour           x hours

Using cross products

3/4 x = 1 * 2/3

3/4x = 2/3

Multiply each side by 4/3

4/3 * 3/4x = 2/3 * 4/3

x = 8/9

8/9 hours

Answer:

Step-by-step explanation:

3/4×=1*2/3 3/4×=2/3 multiply each side by 4/3 4/3* 3/4×=2/3*4/3×=8/9 8/9 hour
