Question

multiply the additive inverse of minus -1 by 7 with the multiple inverse of 21 by 49​

Answer 1

Answer:

Step-by-step explanation:

additive inverse of - 1 / 7 is 1 / 7.

multiplicative inverse of 21 / 49 = 3 / 7 is 7 / 3

(1 / 7) × (7 / 3) = 1 / 3.

Answer 2

1/3 is the solution when we multiply the additive inverse of minus -1 by 7 with the multiple inverse of 21 by 49

Solution:

Given that,

multiply the additive inverse of minus -1 by 7 with the multiple inverse of 21 by 49

To find the additive inverse of a number,  change the sign of the number

$\text{Additive inverse of } \frac{-1}{7} = \frac{1}{7}$

To find the multiplicative inverse, find the reciprocal of number

$\text{Multiplicative inverse of } \frac{21}{49} = \frac{49}{21}$

Multiply the additive inverse of minus -1 by 7 with the multiple inverse of 21 by 49

$\frac{1}{7} \times \frac{49}{21} = \frac{1}{3}$

Thus 1/3 is the solution when we multiply the additive inverse of minus -1 by 7 with the multiple inverse of 21 by 49
