Given : −4/7

To Find : गुणनात्मक प्रतिलोम

Solution:

गुणनात्मक प्रतिलोम = multiplicative inverse

a multiplicative inverse  is basically a reciprocal

Multiplicative inverse of number  is the number which if multiplied by original number result in 1

Let say N is the multiplicative inverse of  -4/7

=> N x (-4/7)  = 1

Multiplying both sides by - 7

=>  N x (-4/7)(-7) = 1 x (-7)

(+ )(+) = +

(-)(-) = +

(+)(-) = -  

(-)(+) = -

=>  N x 4 = -7

Divide  both sides by 4

=>  N x 4 / 4  = -7 /4

=> N = -7/4

-7/4  is the multiplicative inverse of −4/7
