Question

You have 24 homework problems for math class. You finish 1/2 of them during some extra time in class. If you complete 4 more problems while waiting for the bus, what fraction of the 24 problems will remain?

Answer 1

`(8)/(24) =(1)/(3)`

Explanation:

In order to solve this, you just have to add up the fractions and calculate how much is that:

`(24)/(24)- (24((1)/(2) )+(4)/(24) )\\`

Now you just have to add up and then withdraw from the total:

`(24)/(24)- (24((1)/(2) )+(4)/(24) )\\(24)/(24)- (12+4)/(24) \\(24)/(24)- (16)/(24) =(8)/(24)`

SO now we know that he has 8/24 problems to do, if we reduce that we have that he still has to do 1/3 of the problems.

Answer 2

Well you can start by dividing 20 by 2 because that would give you the half that you finished in class 24 divided by 2 =12 if you finish four more you wound have 12-4=8 you have 8 problems left and now you have to find the fraction so start with 8/24 and then simplify your answers would be 1/3
