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.

I thought about the same question a few weeks ago.

There are two ways to think about division. One works for some cases but the second way works for all (including fractions).

1. a / b = c, means that divide a into b parts and each part is c. It works for most cases but not for others, like doesn’t make sense for fractions divided by fractions because you can’t break something up in fractional parts

2. a / b = c, means that you need c number of b’s to make up a

Like 1 div 2 = 1/2 means you need half of 2 to make 1.
And 1/2 div 1/4 = 2 means you need 2 quarters to make a half which also makes sense.
