Question

Lilly let her friend borrow 1/10 of the money in her purse to buy a snack. How do you write the fraction as a decimal?

Answer 1

`0.1`

Explanation:

You may simply input `1 \div 10` on a calculator to get the answer, but in this case it is easy to make the computation: dividing by `10` means to shift the decimal separator one step left, possibly adding zeroes when needed.

So, adding apparently useless zeroes, if you think of `1` as `01.0` and move the decimal separator one step left you get `0.10` which is `0.1`
