Question

What is `90\div 200`?

Answer 1

`9/20` as a fraction, `0.45` as a decimal, `45%` as a percent

Explanation:

Let's represent this as a fraction:

`90/200`

The zero after `90` and the one zero after `200` will cancel out. getting us:

`(9cancel0)/(20cancel0)=9/20`

This is a fraction in simplest form, or if we want it as a percent, we can change the denominator to `100` by multiplying both the top and bottom by `5`. We get:

`45/100`, which is equivalent to `45%`, or `0.45` as a decimal
