Question

Multiple the additive inverse of -1/7 with the multiplicative inverse of 21/49

Answer 1

Step-by-step explanation:

Additive inverse of (-1/7) = 1/7

Multiplicative inverse of 21/49 = 49/21

By multiplying them,

= (1*49)/(7*21) [7 and 49 gets cancelled.. ]

= (7/21)

Hope this helps.....

Answer 2

Step-by-step explanation:

Additive inverse of -1/7=+1/7

Multiplicative inverse of 21/49=49/21.

By multiplying both we get 49/21*1/7=1/3.

Additive inverse is something which is added to the given number to get the resultant as 0.

Multiplicative inverse is something which is multiplied to given number to get the resultant as 1.
