13,491 | 31,778 | \( \frac{A}{10}=\frac{9}{15} \) What is the value of \( A \) ? | \( 6 \) | If you divide 10 by 2 you get ?/5 but as it is ?/10 you would get 6 and if you add 3you get 9 | True_Neither | null |
13,492 | 31,778 | \( \frac{A}{10}=\frac{9}{15} \) What is the value of \( A \) ? | \( 6 \) | If you divide 10 by 2, you get 5, and 5x3=15. Now if I do an inverse operation on 9, which is divide by 3, then double, it is 6. | True_Correct | null |
13,493 | 31,778 | \( \frac{A}{10}=\frac{9}{15} \) What is the value of \( A \) ? | \( 6 \) | If you divide 15 by 3 and times it by 2, you get 10. If you do this to the numerators, the answer is C, 6. | True_Correct | null |
13,494 | 31,778 | \( \frac{A}{10}=\frac{9}{15} \) What is the value of \( A \) ? | \( 6 \) | If you divide 15 by 3, then times by 2 to 15 you get 10 and when you do the same to the 9 you get 3 | True_Correct | null |
13,495 | 31,778 | \( \frac{A}{10}=\frac{9}{15} \) What is the value of \( A \) ? | \( 6 \) | If you divide 15 by 9 you will get 3, but times it by 3, so it is 9. Do the same on the anonymous sidee which is 2 X 3. | True_Neither | null |
13,496 | 31,778 | \( \frac{A}{10}=\frac{9}{15} \) What is the value of \( A \) ? | \( 6 \) | If you divide 9/15 by 3 you get 3/5 then times by 2to get to the denominator ten equals 6/10 | True_Correct | null |
13,497 | 31,778 | \( \frac{A}{10}=\frac{9}{15} \) What is the value of \( A \) ? | \( 6 \) | If you divide 9/15 by 3 you will get 3/5 and in order to get 3/5 with “A” divided by 10 “A” would have to equal 6 | True_Correct | null |
13,498 | 31,778 | \( \frac{A}{10}=\frac{9}{15} \) What is the value of \( A \) ? | \( 6 \) | If you do 3 5ths, then you will get 6 10th, and then 9 15th. | True_Correct | null |
13,499 | 31,778 | \( \frac{A}{10}=\frac{9}{15} \) What is the value of \( A \) ? | \( 6 \) | If you find out what times table it is in, which is 3 5, then you know it's 6 10. | True_Misconception | Irrelevant |
