2 1/3 {4/3-2/5(3/4 + 3/7)}
so start with the inner parenthenses and multiply 3/4 by 7 so it looks like 21/28
and multiply 3/7 by 4 so it looks like 12/28 and then add them together 33/28
so now it looks like this 2 1/3(4/3-2/5*33/28)
multiply 2/3 and 33/28 so first switch 2/3 into 3/2 then divide so it is 11/14 got it?
now it should look like this 2 1/3(4/3-11/14)
do the some thing to make them equal to get 56/42 and 33/42 then subtract them to get 23/42 then multiply by 2 1/3
to get 2 1/90
