Operations with common fractions
For addition or subtraction, find a common denominator first. For multiplication, multiply numerators and denominators; for division, multiply by the reciprocal of the second fraction. Simplify fractions before and after calculating when possible.
Checking
Estimate whether the result should be less than or greater than 1. Convert mixed numbers to improper fractions before multiplication or division and present the final result in its most appropriate simplified form.
