Adding and subtracting fraction word problems (WIP)

LI: to learn fractions of sets
We learnt about fractions of sets. For example we learnt about equations on stuff like how much is 3/4 of 28. After we learnt it we were suggested on doing creations related to fractions. My creation is doing addition and subtraction fraction word problems. When adding or subtracting fractions you should never do anything to the denominator. But should operate with the numerator.
