5.2.5. Divide a Decimal by Another Decimal

Divide a Decimal by Another Decimal

If we have a division problem like 0.8 / 0.2, it is asking “how many times can 0.8 be divided into groups of 0.2”. The answer is 4. However, if we multiplied both the numerator and the denominator by 10, we would get 8 / 2, which would give us the same answer. We can use this strategy to help us divide decimal numbers.
