How do you multiply rational numbers in fraction form?
You simply multiply the nominators (top) and the denominators (bottom):
After this, you might have to simplify if asked to do so.
Here's an example:
Following our rule, we should first multiply the nominators:
After this, we should multiply the denominators:
And then we should divide both these numbers:
If you're asked to simplify this answer to the lowest terms, you should divide both the nominator and denominator by 4 (in this case), because that's the GCD of the two numbers.
