\( \frac{1}{3}+\frac{2}{5}= \)
\( \frac{11}{30} \)
i think the answer is c because 1/3 is 5/15 and 2/5 is 6/15 so when you add them together it is 11/15 and you can't simplify them.

\( \frac{1}{3}+\frac{2}{5}= \)
\( \frac{11}{30} \)
i think this answer, because you have to find a common denominator, and when you have found it you can add the numbers - apart from the denominator because it's the same

i think this because 5x3=15 so you do 5x1=5 and 3x2=6 and 6 plus 5 is 11 so it would be 11/15
