Question

Multiply the additive inverse of -3/7 by the multiplicative inverse of -7/3.

Answer 1

Answer:

- 9/49

Step-by-step explanation:

Additive inverse of -3/7 = 3/7

Multiplicative inverse of -7/3 = - 3/7

= 3/7 × -3/7

= -9/49

Answer 2

Answer:

-9/49

Step-by-step explanation:

• additive inverse = change the sign if it's positive to negative and if it's negative change to positive ( -a/b+(+a/b)=1

additive inverse of -3/7= 3/7

• multiplicative inverse is called reciprocal means numerator becomes denominator and denominator becomes numerator ( a/b×b/a = 0 )

multiplicative inverse of -7/3 = 3/-7 or -3/7

• multiply both digits

3/7×-3/7= -9/49
