Question

क्या-2 5/8का गुणात्मक प्रतिलोम8/21 है? क्यों अथवा क्यों नहीं?​

Answer 1

Given :  -2 5/8का गुणात्मक प्रतिलोम8/21 है

To Find : True or False

Solution:

गुणात्मक प्रतिलोम  = Multiplicative inverse

Multiplicative inverse of any non zero number  is reciprocal of the number

1/a is the multiplicative inverse of a

as a  * 1/a  =  1

-2 5/8

= - 21/8

Multiplicative inverse = 1/(-21/8)  = - 8/21

Hence 8/21 is not Multiplicative inverse of -2 5/8

as if  8/21 is multiplied by -2 5/8 then result is - 1  not 1

Hence -2 5/8का गुणात्मक प्रतिलोम8/21 है is FALSE
