Why do you have to multiply the denominators when multiplying fractions?

Updated: 9/16/2023

If you don't, how would you get a denominator? Also, think of it as, for example, 2/5 OF 5/10. 1/5 of 5/10 is 1/10 so 2/5 of 5/10 is 2/10 or 1/5. That's the concept behind the computation: 2/5 x 5/10=10/50. 10/50 divided by 10 is 1/5.
