how do you reduce a fraction

Dividde both the numerator and denominator by the largest common integer possible. Then cancel them out.

For example, in the fraction 15/25, the largest integer that is divisible evenly into both numerator and denominator is 5. So you would write
15/25 = (5*3)/(5*5) = 3/5
(The 5's cancel out)

You're welcome! I'm glad I could help. Remember, the key to reducing a fraction is finding the largest common factor of the numerator and denominator and dividing both by that number. It's important to simplify fractions as much as possible to make them easier to use in calculations or to compare them. If you have any more questions, feel free to ask!
