Question

Write 0.851 as a fraction in simplest form.

Answer 1

`(851)/(1000)`

Explanation:

First, we can simply multiply that number by 1000, and divide again by 1000 to get a base fraction:

`.851\\\\= (1000)/(1000) * .851\\\\= (1000 * .851)/(1000)\\\\= (851)/(1000)`

851 is a secondary prime, having only two factors, both of which are prime. Those factors are 23 and 37, neither of which is a factor of 1000, so this is already in simplest form.
