You reduce fractions by taking the GCF out of the numerator and denominator.
Example: 10/15
If you know that the GCF is 5 and you subtract it, you're left with 5/10, which can't be right because 5/10 equals 1/2 and 1/2 does not equal 10/15. Subtracting numbers does not leave them in the same proportion.
