Similar fractions are fractions with the same denominator. In order to add or subtract fractions they need to be similar.
If the denominators are the same (which is what I understand by "similar fractions"), just subtract the numerators (the upper part).
Change the whole number into an improper fraction with the same denominator as the fraction and then subtract accordingly
If the fractions have the same denominator, just add or subtract the numerators. 13/20 - 9/20 = 4/20 2/5 + 1/5 = 3/5
First you would want to change the mixed number to an improper fraction. Then you can subtract
Just simply add/subtract the numerators then copy the denominator.

You can subtract the bigger fraction by the smaller fraction and then put a minus sign in front of the answer.

In the same way that you would answer a fraction subtract another fraction. The result could be either positive or negative, just as is the case with negative whole numbers.
You can either convert the decimal to a fraction and then subtract (3/4 - 0.5 = 3/4 - 2/4 = 1/4), OR you can convert the fraction to a decimal and then subtract (3/4 - 0.5 = 0.75 - 0.5 = 0.25).
The difference.
Turn the proper fraction into an improper fraction.
Pie charts make nice fraction diagrams. Each fraction that you subtract is equivalent to taking out a slice of pie.
