Question

. Find the sum of additive inverse and multiplicative inverse of 7.
Find the product of additive inverse and multiplicative inverse of -1/3​

Answer 1

Answer:

BRAINLEST!!

1 The multiplicative inverse of 7 is 1/7..Zero is the additive inverse of itself. The additive inverse of a is denoted by unary minus: −a (see the discussion below). For example, the additive inverse of 7 is −7, because 7 + (−7) = 0, and the additive inverse of −0.3 is 0.3, because −0.3 + 0.3 = 0 .

The opposite (also known as the additive inverse) is the number we have to add to get an answer equal to the additive identity, 0 . Since 13+(−13)=(−13)+13=0 , the opposite of 13 is −13 .Similarly, the multiplicative inverse of 13 is 1⁄13. Another word for multiplicative inverse is 'reciprocal'.

Answer 2

Answer of question 1)

Additive inverse of 7=-7 (because 7+-7=0)

Multiplicative inverse of 7=1/7 (because 7*1/7=1)

Sum of multiplicative and additive inverse of 7:

(-7)+(1/7)

-49+1

7

-48/7 <------- Answer

Answer of question 2)

Addictive inverse = 1/3

Multiplicative inverse = -3/1
