The word "solve" applies to equations.
Should say "calculate" in this instance.
2/3 + 4/5
10/15 + 12/15
22/15
1 7/15

2/3 + 4/5
= (2 x 5)/(3 x 5) + (4 x 3)/(5 x 3)
= 10/15 + 12/15
= 22/15
= 1 7/15

2/3 + 4/5 = 10/15 + 12/15 = 22/15
2008-05-12 11:03 pm
2/3 = 10/15
4/5 = 12/15
2/3+4/5 = 10/15+12/15 = 22/15
22/15 = 1 and 7/15 ~~> mixed number
So the answer is 22/15
or 1 and 7/15

2/3 + 4/5
First, must find a common denominator. In this case it is 15. (3x5)
Now change both fractions to 15ths.
10/15 + 12/15 = 22/15 = 1and 7/15

Just change the denominators so that they're the same.

2/3 + 4/5
= 2x5/3x5 + 4x3/5x3
= 10/15 + 12/15
= 22/15
