first, turn the mixed numbers into a improper fraction. next, find the GCF (greatest common factor) finally, subtract the numerator, and your done! P.s. I'm in middle school too. and i get A+ in math
make the denominator the same then do it like you would normal fractions u make the denominator the same by multipying the top and bottom by same # to get the denominator of one fraction to match the other
