14,092 | 31,778 | \( \frac{A}{10}=\frac{9}{15} \) What is the value of \( A \) ? | \( 6 \) | i worked out that 15 and 10 have a factor of 30 and then you times 9 by 2 and then divide 18 by 3 which is 6 | True_Correct | null |
14,093 | 31,778 | \( \frac{A}{10}=\frac{9}{15} \) What is the value of \( A \) ? | \( 6 \) | i worked this out by converting nine-fifteenths into fifths, which would be three-fifths. therefore, a tenths must be equal to three-fifths as well. so we convert three-fifths into tenths and we get six-tenths. we know that a = 6 | True_Correct | null |
14,094 | 31,778 | \( \frac{A}{10}=\frac{9}{15} \) What is the value of \( A \) ? | \( 6 \) | i worked this question out in my book but i did have to think in this one. | True_Neither | null |
14,095 | 31,778 | \( \frac{A}{10}=\frac{9}{15} \) What is the value of \( A \) ? | \( 6 \) | i would not be able to | True_Neither | null |
14,096 | 31,778 | \( \frac{A}{10}=\frac{9}{15} \) What is the value of \( A \) ? | \( 6 \) | if it was a sequence it would be 3/5 then 6/10 then 9/15 | True_Correct | null |
14,097 | 31,778 | \( \frac{A}{10}=\frac{9}{15} \) What is the value of \( A \) ? | \( 6 \) | if the denominator is 5, then the numerator will be 3. | True_Neither | null |
14,098 | 31,778 | \( \frac{A}{10}=\frac{9}{15} \) What is the value of \( A \) ? | \( 6 \) | if u add 3 on it would get 9 | True_Neither | null |
14,099 | 31,778 | \( \frac{A}{10}=\frac{9}{15} \) What is the value of \( A \) ? | \( 6 \) | if u make the denominator the same then put 18 and divide by 3 u get 6 | True_Correct | null |
