**A reciprocal can also be called a multiplicative inverse.**

**The reciprocal of a number is created by dividing one by the number.**

For example the reciprocal of 8 equals 1/8

**When you have a fraction you can create it’s reciprocal by flipping the fraction**.

For example the reciprocal is 2/3 = 3/2

Or the reciprocal of 3/4 = 4/3

**Any number times its reciprocal equals 1**

**Use a reciprocal when solving an equation when the coefficient of the variable is a fraction.**

2/3x = 4

Multiply both sides by the reciprocal

(3/2*2/3x) = 3/2*4

X = 6

**A reciprocal is also used when you divide fractions**

You Keep Change Flip

2/3 ÷ 3/4 = 2/3 x 4/3
