Question

Given : 1/16 ÷ 1/81 + -1/8
To find : multiplicative inverse
Solution:
a multiplicative inverse is basically a reciprocal
Multiplicative inverse of number is the number which if multiplied by original number result in 1
1/16 ÷ 1/81 + -1/8
1/16 ÷ 1/81 = 81/16
+ -1/8 = - 1/8
81/16 - 1/8
= 81/16 - 2/16
= (81 - 2)/16
= 79/16
