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