13,093 | 31,778 | \( \frac{A}{10}=\frac{9}{15} \) What is the value of \( A \) ? | \( 6 \) | I just simplified 9/15 down and the. made the equivalent of that out of tenths | True_Correct | null |
13,094 | 31,778 | \( \frac{A}{10}=\frac{9}{15} \) What is the value of \( A \) ? | \( 6 \) | I just timed it by 3. | True_Neither | null |
13,095 | 31,778 | \( \frac{A}{10}=\frac{9}{15} \) What is the value of \( A \) ? | \( 6 \) | I knew 5 times 3 is 15. So if the fraction had a denominator of 5, the numerator will be 3. So if the denominator is 10, then the numerator is 6. | True_Correct | null |
13,096 | 31,778 | \( \frac{A}{10}=\frac{9}{15} \) What is the value of \( A \) ? | \( 6 \) | I know 3 or 4 wold not work | True_Neither | null |
13,097 | 31,778 | \( \frac{A}{10}=\frac{9}{15} \) What is the value of \( A \) ? | \( 6 \) | I know 6 over 10 is equivalent to 9 over 15 | True_Correct | null |
13,098 | 31,778 | \( \frac{A}{10}=\frac{9}{15} \) What is the value of \( A \) ? | \( 6 \) | I know it’s c because if I did a/10 x3 = b/30 % 2 = 9 /15 so you do the inverse so my answer is 6 | True_Correct | null |
13,099 | 31,778 | \( \frac{A}{10}=\frac{9}{15} \) What is the value of \( A \) ? | \( 6 \) | I know that 9 fifteens are equivalent to 3 fifths so if you times 3 fifths by 2 it will equal 6 tenths | True_Correct | null |
