24,397 | 33,472 | \( \frac{1}{3}+\frac{2}{5}= \) | \( \frac{11}{15} \) | i think d because you have to convert the denominators so they are the same to add them together | True_Neither | null |
24,398 | 33,472 | \( \frac{1}{3}+\frac{2}{5}= \) | \( \frac{11}{15} \) | 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. | True_Correct | null |
24,399 | 33,472 | \( \frac{1}{3}+\frac{2}{5}= \) | \( \frac{11}{15} \) | i think i know it is c | True_Neither | null |
