\( \frac{1}{3}+\frac{2}{5}= \)
\( \frac{11}{15} \)
i think d because the denominator is 15. 1x5=5 and 2x3=6 5+6=11 and the answer is 11/15.

i think d because when converting both numbers into 15s you get 5/15+6/15 which is 11/15

\( \frac{1}{3}+\frac{2}{5}= \)
\( \frac{11}{15} \)
i think d because you can count in your 3x table and your 5x and when you look at your table you will notice there is 15 in 3 and 5.

\( \frac{1}{3}+\frac{2}{5}= \)
\( \frac{11}{15} \)
i think d is correct, because you need to convert 1/3 into 5/15 (timed by 5) and 2/5 into 6/15 ( timed by 3) them added together becomes 11/15.
