the answer is 11/15. although it may look like we can add 3 and 5 together, this is not how we add fractions with a different denominator. we find the lcd (lowest common denominator). for the values 3 and 5, this value is 15. 3 times 5 is 15, so we multiply 1 by 5, which gives us 5/15. on the other hand, 5 times 3 equals to 15, so we times 2 by 3 to get 6/15. so, 5/15 + 6/15 = 11/15

\( \frac{1}{3}+\frac{2}{5}= \)
\( \frac{11}{15} \)
the answer would be d as 3 and 5 both fit into 15 then that would be the lowest common denominator then you would add 5+6 which would be 11/15
