You do not need a common denominator when multiplying fractions; but
you need it when adding or subtracting fractions.

To multiply fractions, you can follow these steps:
Step 1: Multiply the numerators (the top numbers) of the fractions together to get the new numerator.
Step 2: Multiply the denominators (the bottom numbers) of the fractions together to get the new denominator.
Step 3: Simplify the resulting fraction, if necessary, by finding the greatest common divisor of the numerator and denominator and dividing both by it.
Let's see an example to make it clearer.
Example: Multiply 1/4 by 2/3
Step 1: Multiply the numerators: 1 * 2 = 2
Step 2: Multiply the denominators: 4 * 3 = 12
Step 3: Simplify the fraction, if needed. In this case, the fraction cannot be simplified any further.
Therefore, 1/4 multiplied by 2/3 is equal to 2/12, or simply 1/6.
Remember to simplify the fraction whenever possible to get the simplest form.
