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
