What is the additive and multiplicative inverse of 0.25

The additive inverse is - 0.25.

The multiplicative inverse is 1/0.25, or 1 / (1/4), or 4.

Addative inverse makes it 0

0.25+AI=0

minus 0.25

AI=-0.25

the addative inverse is - 0.25

multiplicatiive inverse is what times that number=1

0.25 times MI=1

divide both sides by 0.25

MI=1/0.25

MI=4

addative inverse is - 0.25

multiplicative inverse is 4
