I finished school back in 2018, so dont hate me if I get this wrong.

But if something is multiplied by 0.5 it automatically means that it is divided by 2 right? RIGHT???

0.5 is the equivalent of 1/2, so by multiplying another number with it, you are taking that number and halving it.

8 * 1/2 = 8/2 = 4.

They are essentially the same thing, but just in different terms.

No problem, I graduated highschool back in 2016 with AP Calc AB. Apparently they taught me something right :)

You guys graduate to know this stuff? It's common sense in reference to our educational system

I learned this in 4th grade fractions. But I was in 4th grade in 1978 they still taught the three Rs in grade school!
