Question

Additive and multiplicative inverse of 0.25

Answer 1

3/4, 4

Explanation:

let

`(25)/(100) + x = 1 \\ (1)/(4) + x = 1 \\ x = 1 - (1)/(4 ) \\ x = (4 - 1)/(4) \\ x = (3)/(4)`

: the additive inverse is 3/4

let

`(25)/(100) * x = 1 \\ (1)/(4) * x = 1 \\ (x)/(4 ) = 1 \\ x = 4`

: the multiplicative inverse is 4
