Question

What is 4.0 divided by 0.05?

Answer 1

80

Explanation:

There are two ways to do this:
`4/0.05`

1) we can think of the `0.05` as a fraction `5/100`. If we then write the fraction as `4/(5/100)` we can use a property of fractions when they are in the denominator, which is, we flip them upside down and multiply by the numerator, making it look like this: `4*100/5=4*20=80`

2) we can multiply the top and bottom of that by 100 leaving us with `400/5=80`
