Decimal Division? I know the answer for "3.6 / 0.04" is "90", but how?
Hi there, so I'm doing a practice test because I want to brush up on math since its been awhile and I came across something I dont even know what it is or called and how to get the answer.
I'm allowed a calculator for the test which is fine and I can get the answer but I want to know what the process is called and how to go about getting the answer, here's the problem, with a multi-choice to choose from.
Q. 3.6 / 0.04
144
9
14.4
90
180
I know the answer is 90 but how? And what is this even called. Decimal division? The prep test shows the explanation...
3.6 / 0.04
= 36 / 0.4
= 360 / 4
= 90
Here, I know we can move the decimal 1 place to the right for both sides, but then where does the 0 come from in (360). I think to make the .4 a whole number you must times both sides by 10 because the 4 is in the tenths after the decimal?
Thanks for any help in advance.![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
