Is it 'MIXED NUMBERS?'
ex:
4 3/5 - 2 1/5
-Since it is similar fractions, only subtract the whole numbers and the numerators. = 2 2/5
4 3/5 - 2 1/4
-Since it is dissimilar fractions. Find the Least Common Denominator (LCD) of the fractions so the denominators will be the same. 3/5 = 12/20 1/4 = 5/20 because the LCD is 20.
-Then subtract the whole numbers and the numerators.
= 4 12/20 - 2 5/20 = 2 7/20
