Question

How do you divide `0.85\div 5`?

Answer 1

0.17

Explanation:

`0.85` can be written as `85/100`. That's where the decimal point comes from.
The number of zeroes is the same as the number of digits after the decimal, if the zeroes are in the denominator.

So, `0.85div5` can be written as `85/100xx1/5 = cancel(85)^17/100xx1/cancel(5)_1 = (17xx1)/(100xx1) = 17/100 = 0.17`
