\( \frac{A}{10}=\frac{9}{15} \) What is the value of \( A \) ?
\( 6 \)
First we have to figure out the denominator then apply that to the numerator. 2/3 of 15 is ten, so 2/3 of 9 is 6.

First, I found the LCM and turned the fractions into thirtieths. Then, I found out that 18 = 3a so 18 divided by 3 is 6 so A must be 6.

\( \frac{A}{10}=\frac{9}{15} \) What is the value of \( A \) ?
\( 6 \)
First, you find a common factor of the denominators (10 and 15) which is 5. To simplify 9/15 to fifths we divide by 3, which gives 3/5. To simplify A/10 to fifths we divide by 2, which gives A/2/5. A divided by 2 must give 3, so it must be 6.

From 10 to 15 you went from 2/3 to 3 1/3. So 1/3 is 5 for the denominator. And 3 is 3 because 9 divided by 3 = 3. Meaning if you do 3 x 2 you get the answer 6.

From 10 to 15 you went from 2/3 to 3/3. 1/3 is 5 for the denominator. For the numerator 1/3 is 3 because 9 divided by 3 is 3. Meaning if you do 3 x 2 you get the answer 6.
