Answer 2

-0.78125 or
`(25)/(32)`

Explanation:

Rewrite the decimal number as a fraction with 1 in the denominator

0.78125 =
`(0.78125)/(1)`

Multiply to remove 5 decimal places. Here, you multiply top and bottom by 105 = 100000

`(0.78125)/(1) . (100000)/(100000) = (78125)/(100000)`

Find the Greatest Common Factor (GCF) of 78125 and 100000, if it exists, and reduce the fraction by dividing both numerator and denominator by GCF = 3125,

`(78125)/(100000) . (3125)/(3125) = (25)/(32)`
