Answer :
( 5 + 2 ) + ( 3 / 8 + 3 / 12 ) = 7 + ( 9 / 24 + 6 / 24 ) = 7 + 15 / 24 = 7 + 5 / 8 = 7 5/8;
The fractional portion is 5 / 8 = 0.4
The fractional portion is 5 / 8 = 0.4
First we need to find the common denominator for 8 and 12.
8 = 8, 16, 24
12 = 12, 24
So we have 24 as our common denominator.
5 3/8 = 5 9/24
2 3/12 = 3 6/24 now we can add.
8 15/24
So that would be your answer 8 15/24
Hope this helps you. :-)
