Question

ii) Write the additive inverse of 2
by
7

and multiplicative inverse of 7
by
9​

Answer 1

Answer:

Additive inverse of 2/7 = -2/7                          (2/7+-2/7=0)

Multiplicative inverse of 7/9=9/7                    (7/9 x 9/7= 1)

Answer 2

Step-by-step explanation:

additive inverse of 2/7 = -2/7

2/7+x= 0

x=-2/7

multiplicative inverse of 7/9 = 9/7

7/9 ×x =1

x=9/7
