Subtracting fractions

 

It is a three step process to subtract fractions.

  1. Rename with common denominators
  2. Subtract whole numbers and numerators
  3. Simplify (if needed)
 The problem $$5\frac{5}{6}\,-\,2\frac{2}{9}\,=$$
Rename with common denominators $$5\frac{15}{18}\,-\,2\frac{4}{18}\,=$$
Subtract $$3\frac{11}{18}$$
Simplify  not needed this time

 


Here is another example.

$$5\frac{2}{3}\,-\,2\frac{1}{6}\,=$$
