math is hard : memes

,25/,5 x 100/100 = 25/50 = 1/2

Why was that hard?

100/100 = 1, because any number divided by itself is 1.

And any number multiplied by 1 is still that number.

TBH, I moved the decimal over 2 places on the numerator and denominator and simplified 25/50 to 1/2 because It is easier to do in my head. Some of the other paths are too complicated when I am going to sleep.

Man, I thought this is an ADHD meme when trying to sleep and your brain starts to do random shit.

N / (1/2) = 2N/1 = 2N

That's 2x2=4 level of stupid.

(1/4) ÷ 1/2 = 2/4 = 1/2 = 0.5

You have one apple. You divide it into quarters, so that you have 0.25 of an apple. Now divide it in half. So yes well technically you do have one half of 0.25 (and 0.5 is the answer that a calculator will return) what you actually have is 1/8 of an apple (0.125).

This is what pisses me off about Matt half the time. You end up with something that in the abstract makes sense because it's just numbers, but then if you try to make it make sense in real life it's stupid.

Fractions are just funky when dividing. Dividing by 0.5 is the same multiplying by 2.

Your analogy is really close, but backwards is all. If you have a quarter of an apple. In order to get half a whole apple, you need another quarter. Two quarters make a half, so dividing a quarter by 0.5 gives you 2 quarters. Dividing a quarter by 2 gives you 0.5 of the original quarter which is your 1/8th
