Question

Write -90.85 as a mixed number in simplest form.

Answer 1

-90.85 = -90 85/100
-90 85/100 = -90 17/20

Answer 2

Well, -90 would obviously be the whole number.
So,
`-90 (unknown)/(unknown)`.
And now, 85 would be a part, so that would be the numerator. The last number of 85, 5, is in the hundredth place, so the denominator would be 100.

Which would get us,
`-90 (85)/(100)`

Now simplify.
5 can go into both numbers.

85/5 = 17
100/5 = 20

So you get
`(17)/(20)`

Your final answer is
`-90 (17)/(20)`
