Question

a tractor driver plowed 1/5 of a field on the first day, and 1/4 on the second day. How much did he plow in the first two days? How much does he still need to plaw?

Answer 1

1) (9/20)x 2) (11/20)x

Explanation:

x = total area of the field.

In the first two days he plowed (1/5)x + (1/4)x = (9/20)x

He still needs to plow x - (9/20)x = (11/20)x
