Question

A builder was building a fence in the morning he work for 2/5 of an hour in the afternoon he worked for 9/10 of an how many long in the morning did he work in the afternoon

Answer 1

He works 24 mins in the morning.

He works 54 mins in the afternoon.

And he worked 30 mins longer in the afternoon.

division equation: 9/10 x 5/2 = 45/20 =9/4 = 2 1/4

(those are fractions).

Explanation:

i dont really know what youre asking but first you would do 2/5 time 60 mins and that is 24 mins. And then you would do 9/10 times 60 mins which is 54 mins. Then subtract the difference. 54-20 which is equal to 30.
