Hope this helps :)
Find a common denominator first
2 24/40 - 1 15/40 = 1 9/40
it is already in simplest form so you can not reduce it
To find X, we can divide 5 into 40.
40 divided by 5 is 8.
Now we can do 5 x 8. That is 40.
X=40
OR we can do it another way.
40 divided by 5 is 8.
Cross out 5 divided by 5.
Now we have 8. Still.
X is 8
