hi,

what happen when we multiply decimal by a percentage and it is different from the concept of regular multiplication numbers concept

for example

multiply 3 * 4 is 3 + 3 + 3 + 3 = 12 or 4+4+4 = 12

the clearest explanation of this simply mean 4 copies of 3 added togather or 3 copies of 4

but

when we multiply

100 * 50% it's clearly mean 100 * 50/100 = 100

what is the deep explanation of that mean?

Percent means per 100 so you can always replace % by /100

That's all really.
