BEFORE WE START: We are here to help you! Do NOT be afraid to ask questions. There are no dumb questions! The only dumb thing to do is not ask for help when you are stuck.

Lesson 1: Fractions  Fractions are not scary! Lets take this step by step  We’ll be learning how to add, subtract, multiply, and divide fractions  Adding with common denominator This is how we do it!

Lesson 1: Fractions (continuing)  Adding with unlike denominators This is how we do it!

Lesson 1: Fractions (continuing)  Multiplication (multiplying)  When multiplying, the denominators do not have to be like terms. They can be different numbers  Note that 3x5=15, and that 8x9=72. We get the answer shown above by Simplifying the fraction. This is how we do it!

Lesson 1: Fractions (continuing)  Dividing Fractions This is how we do it!  To get this answer there is a shortcut. We can multiply by the reciprocal of the 2 nd number. X  After setting up the second number up as a reciprocal, multiply straight through
