Question

Find the additive and multipliactive inverse for each number: 3A) 1.25

Answer 1

additive inverse means that the numbers that when added will equal to 0

so :
1.25 + x  = 0
           x  =  -1.25

meanwhile, multiplication inverse means if multiplied, the numbers will equal to 1

So :

1.25 x   = 1
        x   = 1/1.25
 
        x  = 0.8

Hope this helps
