Questions about fractions
Why must the parts be equal?
The denominator names the size of each equal part of a whole. Unequal pieces cannot be counted as identical fractions of that whole.
Do different denominators always need changing?
For addition and subtraction, a common denominator makes the units match. Multiplication and division follow different rules.
