Hopefully no important grouping symbols were left out when you asked the question. Here's what you asked: 1/2+2/3+1/8=
(1/2)+(2/3)+(1/8)=
12/24+16/24+3/24=
31/24
17/24
It is: 1/3 plus 1/3 = 2/3
11/12
((2 plus (1 over 4)) plus 3) plus (7 over 8) = 6.12500
2/3 + 1/6 + 1/6 = 1
1
2/5 plus 1/3 plus 5/6 is equal to 1.57 or 1 57/100
2/3 + 1/4 + 2/3 = 4/3 + 1/4 = (16/12) + (3/12) = 19/12 = 1 and 7/12
The answer is 1/2 plus 3/10 = 4/5 in its simplest form
2/3
1 13/20
1 over 1
2 1/3
