12,591 | 31,778 | \( \frac{A}{10}=\frac{9}{15} \) What is the value of \( A \) ? | \( 6 \) | 2/3s of 15 is 10, and 2/3s of 9 is 6, therefore the answer is 6/10. | True_Correct | null |
12,592 | 31,778 | \( \frac{A}{10}=\frac{9}{15} \) What is the value of \( A \) ? | \( 6 \) | 3 /5 is the same as 9/15 and 3/5 is the same as 6/10 | True_Correct | null |
12,593 | 31,778 | \( \frac{A}{10}=\frac{9}{15} \) What is the value of \( A \) ? | \( 6 \) | 3 goes into 9 and 15 3 and 5 times so it would be 3 over 5 and you double that to get 6 over ten | True_Correct | null |
12,594 | 31,778 | \( \frac{A}{10}=\frac{9}{15} \) What is the value of \( A \) ? | \( 6 \) | 3 times 2 = 6 because 6 times 3 is 9 and 9 times 5 is 5. so you can do 3x2=6. | True_Neither | null |
12,595 | 31,778 | \( \frac{A}{10}=\frac{9}{15} \) What is the value of \( A \) ? | \( 6 \) | 3/5 can also be put as 6/10 or 9/15 | True_Correct | null |
12,596 | 31,778 | \( \frac{A}{10}=\frac{9}{15} \) What is the value of \( A \) ? | \( 6 \) | 3/5 into tenths is 6/10 and into 15ths is 9/15 | True_Correct | null |
12,597 | 31,778 | \( \frac{A}{10}=\frac{9}{15} \) What is the value of \( A \) ? | \( 6 \) | 3/5 is equal to 6/10 which is equal to 9/15 | True_Correct | null |
12,598 | 31,778 | \( \frac{A}{10}=\frac{9}{15} \) What is the value of \( A \) ? | \( 6 \) | 3/5 is equal to 9/15 so that also means 3/5 is equivelent to 6/10 and by using this evidence , a is equal to 6. | True_Correct | null |
12,599 | 31,778 | \( \frac{A}{10}=\frac{9}{15} \) What is the value of \( A \) ? | \( 6 \) | 3/5 is in its simplest form 3/5=6/10 | True_Correct | null |
