### Subtracting Fractions with Unlike Denominators

You must find a common denominator
and use an eqivalent fraction.

Examples.
3/4 - 1/2 = ?

4-4,8,12,16
4 is their common denominator.
2-2,4,6,8,

So you change 1/2 into 2/4 since what ever you do to the bottom u do to
number.

3/4 - 2/4 = 1/4

(More examples)
2/3 - 1/4 = 8/12 - 3/12
5/12

3/4 - 1/8 = 6/8 - 1/8
5/8

Unit fraction
A fraction with a numerator of 1.
Examples.
1/2, 1/3, 1/4, 1/10, 1/100, 1/anything.
