Start with the reverse. If you had half a pizza and you wanted to divide it by quarters of a pizza, you’d be able to do it 4 times (there are four quarter slices in a half pizza).
But with this we’re asking how many half-pizza slices are in a quarter-pizza slice. The answer is that there’s half of one (half of a half is a quarter).
When you divide by 0.5 (or any number) you are saying how many 0.5s (or other number) can I fit in that first number. You can fit half of a 0.5 in 0.25
I understand this mathematically, but can somebody explain it logically?
Multiplying by 0.5 halves. Dividing would double the number. 0.25 doubled is 0.5.
Sleep well!
y/x = x with y = x*x because 0.25 is 0.5 squared.
from the “wow factor” it’s the same as writing: 9/3 = 3 - not very wow at all
0.25 is half of 0.5

A quarter is half of a half
