Question

-2.105 as a fraction?

Answer 1

The easiest way is if it doesn't need to be simplified. Multiply -2.105 by
`(1000)/(1000)`. You get the fraction
`-(2105)/(1000)`. While this is technically the answer, you can simplify this down to
`(421)/(200)`. Because 421 is a prime number, this can not be simplified any further. Therefore, the solution is
`(421)/(200)`.


`(421)/(200)`.
