5/10+12/16+(15/20-4/16)
Well you need to solve in the parentheses first, by making them common denominators.
(15/20 - 4/16)=(60/80 - 20/80)
Then subtract.
(40/80)
then simplify.
(1/2)
Next make all the fractions with common denominators.
5/10 + 12/16 + (1/2)=
40/80 + 60/80 + (40/80)
or 4/8 + 6/8 +(4/8)=?
Then you finish adding
Hope this helps
