Question

011. Find the sum of Additive inverse and Multiplicative inverse of 7/3
Q12. Solve: 0,25 ( 8x -0,5) = 7.5​

Answer 1

Answer:

3/7     -7/3

7.625/2 = x

Answer 2

Answer:

*additive inverse means "The number which is added to given number so the result is 0."

*Multiplicative inverse means"The number which is multiplied to a given number so the result is 1".

In this question given number is 7/3

*According to additive inverse concept 7/3 +x=0.

Therefore x=–7/3.

*According to multiplicative inverse concept 7/3 ×y=1.

Therefore y=3/7.

Therefore sum of Additive inverse and Multiplicative inverse of 7/3=x+y = –7/3+3/7 = 3/7–7/3 = 9–49/21 = 40/21.
