13,192 | 31,778 | \( \frac{A}{10}=\frac{9}{15} \) What is the value of \( A \) ? | \( 6 \) | I think it is c because I did 10 x 9 to get 90 then divided it by 15 to get 6 | True_Correct | null |
13,193 | 31,778 | \( \frac{A}{10}=\frac{9}{15} \) What is the value of \( A \) ? | \( 6 \) | I think it is c because i did 3 divide by 9 and then i got 3 then i did 3 times by 2 which gave me 6. | True_Correct | null |
13,194 | 31,778 | \( \frac{A}{10}=\frac{9}{15} \) What is the value of \( A \) ? | \( 6 \) | I think it is equivalent because 9/15and if I divid 9/15 by three it will make 3/5 so 3/5 is like 6/10 | True_Correct | null |
13,195 | 31,778 | \( \frac{A}{10}=\frac{9}{15} \) What is the value of \( A \) ? | \( 6 \) | I think it this because its multiplyed by three | True_Misconception | Irrelevant |
13,196 | 31,778 | \( \frac{A}{10}=\frac{9}{15} \) What is the value of \( A \) ? | \( 6 \) | I think it would be 6 because both of them simplified are 3/5. | True_Correct | null |
