Question

Find the product of the additive inverse of 4/7 and the additive inverse of -7/8 ​

Answer 1

Answer:

-1/2

Step-by-step explanation:

Given :-

4/7 and -7/8

To find :-

Find the product of the additive inverse of 4/7 and the additive inverse of -7/8 ?

Solution :-

Given number = 4/7

Additive inverse of 4/7 = -4/7

and

Another given number = -7/8

Additive inverse of -7/8 = 7/8

Their product = (-4/7)× (7/8)

=> (-4×7)/(7×8)

=> -28/56

=> -1/2

Answer:-

The product of the additive inverse of 4/7 and the additive inverse of -7/8 is -1/2

Used formulae :-

• Additive inverse of a = -a

• Additive inverse of a/b = -a/b

Points to know :-

• The sum of two rational numbers is equal to zero then they are called Additive inverses to each other.

• a+(-a) =(-a)+a = 0

a is the Additive inverse of - a and additive inverse of a is -a.

• 0 is the additive identity elements in rational numbers .
