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

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).

Step-by-step 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.

1/800 is the right answer
