13,692 | 31,778 | \( \frac{A}{10}=\frac{9}{15} \) What is the value of \( A \) ? | \( 6 \) | a would be 6 because the other fraction before it, would be 3 5 | True_Correct | null |
13,693 | 31,778 | \( \frac{A}{10}=\frac{9}{15} \) What is the value of \( A \) ? | \( 6 \) | a/10 = 9/15 then i did 9/15 bigger to 18/30 so I saw that 30 dived by 10 is 3 so I dived 18 by 3 to get 6 | True_Correct | null |
13,694 | 31,778 | \( \frac{A}{10}=\frac{9}{15} \) What is the value of \( A \) ? | \( 6 \) | a/10 equals 3a/30, which equals 18/30, so 3a is 18, meaning a is 6. | True_Correct | null |
13,695 | 31,778 | \( \frac{A}{10}=\frac{9}{15} \) What is the value of \( A \) ? | \( 6 \) | a/10=9/15 b=30 18 divided by 3=6 | True_Correct | null |
13,696 | 31,778 | \( \frac{A}{10}=\frac{9}{15} \) What is the value of \( A \) ? | \( 6 \) | adam helped me but didnt just tell me | True_Neither | null |
13,697 | 31,778 | \( \frac{A}{10}=\frac{9}{15} \) What is the value of \( A \) ? | \( 6 \) | answers to book also have a nice day miss :d | True_Neither | null |
13,698 | 31,778 | \( \frac{A}{10}=\frac{9}{15} \) What is the value of \( A \) ? | \( 6 \) | as 10 is 2/3 of 15 so 6 is 2/3 of 9 | True_Correct | null |
13,699 | 31,778 | \( \frac{A}{10}=\frac{9}{15} \) What is the value of \( A \) ? | \( 6 \) | as it goes up in 5's you take 3 off | True_Neither | null |
