4/5 + 1/3 + 3/4
First get a common denominator.
48/60 + 20/60 + 45/60
Now add the numerators and put the sum over the common denominator
48 + 20 + 45 = 113
113/60
Now check to see if it can be simplified, but the answer is no, it is already in simplest form. Change it to a mixed number if you want to.
113/60 = 1 and 53/60
2 & 1 over 4 (2.25)
((2 plus (1 over 4)) plus 3) plus (7 over 8) = 6.12500
2 over 3 plus 4 1 over 4 = 59/12 or 411/12
1/3 + 1/4 = 7/12
2/3 + 1/4 + 2/3 = 4/3 + 1/4 = (16/12) + (3/12) = 19/12 = 1 and 7/12
2 & 1 over 4 (2.25)
1
((2 plus (1 over 4)) plus 3) plus (7 over 8) = 6.12500
1/6 + 1/3 + 1/4 = 2/12 + 4/12 + 3/12 = 9/12 = 3/4
2 over 3 plus 4 1 over 4 = 59/12 or 411/12
1/3 + 1/4 = 7/12
2/3 + 1/4 + 2/3 = 4/3 + 1/4 = (16/12) + (3/12) = 19/12 = 1 and 7/12
11/12
1/3 + 1/4 = 4/12 + 3/12 = 7/12
3 1/4
1 and 1 over 4
3 and 1 over 12
