To multiply fractions, line them up and multiply straight across
5/6 × 4/5 = 20/30 = 2/3
Cancel method
We can save work when multiplying fractions if we cancel first. Canceling is a way to simplify fractions before we multiply. Find one numerator and one denominator that are divisible by the same number. You must always cancel diagonally, never horizontally.
Dividing fractions
To divide one fraction by another, just invert the second fraction and multiply.
2/3 ÷ 3/4 is the same as 2/3 × 4/3 = 8/9
