Eli5 What really is a fraction TIMES a fraction?! It makes NO sense.

I am reteaching myself math, but something is bugging me soooo bad and I can’t find the answer. What is a real life example of multiplying a fraction by a fraction? I was wondering why .05 to the 5th exponent would get smaller not bigger. This is driving me bonkers.

Sure 1/2 makes sense, but how about 1/2 times 3/5 in real life?!?

Edit: OMFG. Math is cool and makes sense. Finally, I’m 28. Thank you all!!!!

Edit: I was given an AP Scholar award, but it was not for math.

* * * The best explanation goes to the person who explained “times” and “of” were synonomous!!!! * * *

NOW EXPLAIN THIS: How am I in the 99.9th percentile for arithmetic, but suck at math?! Do I have potential? Am I still gifted in “math” or are math and arithmetic too separate things. A professor told me they are different parts of the brain.

You have one (1/1 or 1.0) pie. I cut it in half (0.5 or 1/2) and take that piece away.

You now have 1/2 of a pie. I cut that piece in half (0.5) and take that piece away.

You now have 1/4 of the pie. 0.5 * 0.5 = 0.25. 1/2 * 1/2 = 1/4.

Another way to think of it is multiplying fractions is the same as dividing. 1/2 is another way of expressing 1 divided by 2
