Question

help I need urgently​

Answer 1

all these questions are from icse 8th class

and all are simple questions.

Step-by-step explanation:

additive inverse.

(i) 2/8+(-2/8)=0

then -2/8 is the additive inverse of 2/8

(ii) -5/8+5/8=0

then 5/8is the additive inverse of-5/8

(iii) -6/-5+(-6/5)=0

then -6/5 is the additive inverse of-6/-5

and so on.

verify. -(-x) =x

(i) x=11/15

-(-11/15)=11/15

from -×-=+

and so on.

multiplicative inverse

(i) -13×(-1/13)=1 then -1/13is the multiplicative inverse of-13.

multiplicative inverse of any number is their reciprocal.

thank you
