Mr. pham mowed 2\7 of his lawn. his son mowed 1\4 of it. who mowed the most. how much of his lawn still needs to be mowed.

The father did more.

13/28 needs to be mowed which is 0.4643 of the lawn needs to be mowed.

Step-by-step explanation:

The best way to compare the two is to change them to decimals. That will at least answer who mowed the most.

Father: 2/7 = 0.2857

Son: 1/4 = 0.25

Since the father mowed 2/7 of the lawn, he mowed the most.

You can use the decimals to get the second part.

Together they did 0.25 + 0.2857 = 0.5357

The amount of the lawn left is 1 - 0.5357 = 0.4643

If you must have this in fractions then

1/4 + 2/7 = 7/28 + 2*4/28 = 7/28 + 8/28 = 15/28

15/28 = 0.5357 which is just what we got above.

Amount left to do = 1- 15/28 = 13/28

13/28 = 0.4643 which is what we got about.
