How do I divide Decimals?

For example:

30.72

÷ 9.60 and 22.0 ÷ 2.0 and 2.7 ÷ 0.9 You don't have to answer all three, just pick one or do all three if you want, would appreciate that. Just need a simple explanation on how to divide decimals.

That is a long way to divide, I don't have that time but luckly division works just the same with decimals as with normal numbers apart from the decimal points which is okay because I'll have multiple choice.

Not really sure what your getting at there, I mean, that requires too much thinking when it's not needed.

I know what I'm doing now, thanks though.

He's basically asking, what is 11x2?

You can multiply the decimal out of the numerator and denominator. For example:

I thought trailing zeros after the decimal place counts as a significant digit? So 9.60 would be 3 significant digits which means the answer is 3.20? Or is this not correct

Don't forget, the right hand side of the decimal point is the fractional part. So 0.2 is equal to . Which is also equal to 0.20, from which can also be regarded as 20/100 simplifies to 1/5.
