1/3 + 2/5
First, I'l make the denominators be equal (remember, it's numerator/denominator):
1/3 is equal to 5/15 (divide by 5 on denominator and numerator and it'll be 1/3)
2/5 is equal to 6/15 (divide by 3 on denominator and numerator and it'll be 2/5)
Now I have 5/15+6/15=11/15
There, the answer's 11/15
