Question

You paint 1/2 wall in 1/4 hour. At that rate how long will it take you to paint one wall?​

Answer 1

30 minutes

A quarter of an hour is 15 minutes, because 60÷4=15.

So, this means that half of a wall equals to 15 minutes.

If you painted half of a wall, you have another half remaining.

Therefore, 2×15=30

30 minutes is the answere

Answer 2

1/2 hr.

Explanation:

Make a whole number of the wall. In this case, multiply by 2:

1/2 x 2 = 2

Because you multiplied 2 to the wall, you must also multiply 2 to the hours:

1/4 x 2 = 2/4

Remember to simplify:

(2/4)/(2/2) = 1/2

It will take you 1/2 hr to paint one wall.
