Explain how to expand the fraction 4/5 into a fraction with 15 as a denominator.

15/5 = 3

3 * 4 = 12

4/5 = 12/15

Thanks! :)

You're welcome.

To expand the fraction 4/5 into a fraction with 15 as a denominator, you need to multiply both the numerator and the denominator by the same value to maintain the equality.

Step 1: Determine the multiplication factor needed to obtain the desired denominator. In this case, you want to reach a denominator of 15. Since 15 is divisible by 5, you need to multiply both the numerator and denominator by 3.

Step 2: Multiply the numerator (4) by the same value used in Step 1, which is 3. 4 * 3 = 12.

Step 3: Multiply the denominator (5) by the same value used in Step 1, which is 3. 5 * 3 = 15.

So, to expand 4/5 into a fraction with 15 as a denominator, you can multiply both the numerator and the denominator by 3. This results in the fraction 12/15.
