You don't need a common denominator for multiplying fractions.
4/5 * 3/4 = 12/20 = 3/5
Thanks, I always get confuse.
You're welcome.
Yes, your calculation is correct. The answer to 4/5 multiplied by 3/4 is indeed 12.
To explain how you arrived at this answer, let's break it down step by step:
First, you multiplied the numerators together: 4 * 3 = 12.
Next, you multiplied the denominators together: 5 * 4 = 20.
This gives you the fraction 12/20, which is already in its simplest form.
However, you further simplified it by dividing both the numerator and the denominator by their greatest common divisor of 4.
12 divided by 4 is 3, and 20 divided by 4 is 5.
Thus, the fully simplified fraction is 3/5.
Therefore, 4/5 multiplied by 3/4 is equal to 3/5 or simply 0.6 when expressed as a decimal.
