I have been trying to find a solution to this problem I just encountered. So, I can split up a decimal multiplication if I had say: $2.4 * 4.3$ I could do $(2*0.3)+(2*4)+(0.4*4)+(0.4*0.3)$. This works fine. But when I try to do the same sort of thing for division it does not work at all.
So if i have $8000 / 39.8$ and I want to make it so that I can do $(8000/40)-(8000/0.2)$. It doesn’t work at all. I have been trying to come up with other solutions to do this such as $(8000/39)-(8000/0.8)$ etc, I am pretty sure I am going about this all wrong, but could maybe someone help or give me a hint in the right direction? Thanks.
