53%2F4 - 22%2F5
:
Convert both fractions to improper fractions. Multiply the whole number times the
denominator and add the numerator
23%2F4 - 12%2F5
:
They need to have a common denominator, 20 is a multiple of both denominators
20/4 = 5 and 20/5 = 4, so we have
5*23%2F20 - 4*12%2F20
which is
115%2F20 - 48%2F20 = 67%2F20
:
Convert this to a mixed number, divide 20 into 67, the remainder is the fraction
37%2F20
