Question:
Find the multiplicative inverse of the following: (i) 13/15 (ii) 1/5 (iii) (5/8) × (3/7) (iv) 25/5 (v) 5/25
Solution:
Multiplicative inverse of a number P is 1/P as P × 1/P = 1
(i) Multiplicative inverse of 13/15 is 15/13
(ii) Multiplicative inverse of 1/5 is 5
(iii) (5/8) × (3/7) = 15/56. Multiplicative inverse = 56/15
(iv) 25/5 = 5. Multiplicative inverse = 1/5
(v) Multiplicative inverse of 5/25 is 25/5.
