14,191 | 31,778 | \( \frac{A}{10}=\frac{9}{15} \) What is the value of \( A \) ? | \( 6 \) | the answer is 6 because you divide 10 by 15 then times it by 9 | True_Neither | null |
14,192 | 31,778 | \( \frac{A}{10}=\frac{9}{15} \) What is the value of \( A \) ? | \( 6 \) | the answer is c because 15 divided y 10 is 2.5 to figure out test each option by multiplying it by 1.5 and then you can see which one gives you 9 | True_Correct | null |
14,193 | 31,778 | \( \frac{A}{10}=\frac{9}{15} \) What is the value of \( A \) ? | \( 6 \) | the answer is c because 9x10 is 90 and 90 divided by 15 is 6. | True_Correct | null |
14,194 | 31,778 | \( \frac{A}{10}=\frac{9}{15} \) What is the value of \( A \) ? | \( 6 \) | the answer is c because...
15/3 = 5
9/3 = 3
5x2 = 10
3x2 = 6
so a = 6 | True_Correct | null |
14,195 | 31,778 | \( \frac{A}{10}=\frac{9}{15} \) What is the value of \( A \) ? | \( 6 \) | the common denominator is 30 and the 9 will become 18 so we have to do 10x3 to get 30, which is 6x3. so the answer is 18 because the common multiple of 30 is 30, and because 9 is equal to 18. | True_Correct | null |
14,196 | 31,778 | \( \frac{A}{10}=\frac{9}{15} \) What is the value of \( A \) ? | \( 6 \) | the common denominator is 30 so the second fraction =18/30. so to make the first fraction the same i times by 3. 18 / 3 = 6 | True_Correct | null |
14,197 | 31,778 | \( \frac{A}{10}=\frac{9}{15} \) What is the value of \( A \) ? | \( 6 \) | the correctt answer is a. | True_Neither | null |
14,198 | 31,778 | \( \frac{A}{10}=\frac{9}{15} \) What is the value of \( A \) ? | \( 6 \) | the denominator needs to be 30 for both.
9/15 = 18/30. A/10 = 18/30.
so because you have multiplied 10 by 3, 18/3 = 6. | True_Correct | null |
14,199 | 31,778 | \( \frac{A}{10}=\frac{9}{15} \) What is the value of \( A \) ? | \( 6 \) | the equivilant fraction is 3/5 and times that by 2. | True_Correct | null |
