how to make fraction into a mixed number
Let us start with an improper fraction, say, 73/7.
Subtract 70 from the numerator.
You subtract 70 because that is the biggest multiple of 7 (the denominator) which is smaller than the numerator. We then write,
73/7 = (70 + 3)/7
(70 + 3)/7 = 70/7 + 3/7
70/7 + 3/7 = 10 + 3/7
10 + 3/7 = 10 3/7, as a mixed fraction
