Answer 1

Answer:

The answer is -1

Step-by-step explanation:

➙ Additive inverse of (-5/7)

●let x, be the additive inverse of (-5/7)

⇒-5/7+x=0

⇒ x=5/7

⇒ -5/7 is 5/7

➙ Multiplicative inverse of (-5/7)

● let y, be the multiplicative inverse of (-5/7)

⇒ -5/7 × y= 1×y= -7/5

⇒ -5/7 is -7/5

⇒ 5/7 × -7/5 = -1✓✓
