Mr. Doyle mowed 2\5ths of his lawn. His son mowed 1\3rd of it. Who mowed most of the lawn? How much of the lawn still needs to b
kondor19780726 [428]

Answer:

Step-by-step explanation:

Dad:  2/5

Son:  1/3

<u>Who mowed most of the lawn? </u> Dad, of course.  2/5 is larger than 1/3.  2/5 is 40% and 1/3 is 33.333%

<u>How much of the lawn still needs to be mowed?  </u>

 2/5 + 1/3 + X = 1  [1 means the whole lawn.  X is the remaining portion.]

6/15 + 5/15 + X = 1   [Convert each fraction so that they have a com,mon denominator.  This also shows that 2/5 (6/15) is larger than 1/3 (5/15).

11/15 + X = 1

X = 1 - 11/15

X = 4/15 left to be mowed.

<u>How much does Mr. Doyle have left to mow?</u>

We'll assume each rate is the same, 2/5 for Dad and 1/3 for son.

4/15 left to be mowed.

Dad will mow 2/5 of 4/15, so (2/5)*(4/15) = 8/75 left of the original yard

Son will mow 1/3 of 4/15, so (1/3)*(4/15) = 4/45 left of the original yard
