Operations with Fractions and Mixed Numbers

Fractions feel intimidating, but every operation has its own short recipe, and you only ever use one recipe at a time.

Multiplying is the easiest. Adding takes one setup step. Dividing is just multiplying with a tiny flip.

This is a Part I skill: no calculator allowed on the real test, so everything here uses small, friendly numbers you can handle with a pen and a little patience.

Quick vocabulary:

• The numerator is the top number (how many parts you have).
• The denominator is the bottom number (how many parts make a whole).
• A mixed number is a whole number next to a fraction, like 213.
