Question

(1) Reciprocal of additive inverse of 7.5 is _________

(a) -2/15 (b) 10/23 (c) 23/10​

Answer 1

Step-by-step explanation:

additive inverse is inverse of the number which gives the addition a nill result

x= 7.5

let y is the number which gives 0 on addition with x

x+y =0

7.5 + y= 0

y = -7.5

inverse of y is the additive inverse

then,

1/y = 1/-7.5

=> 1/y = -2/15
