Question

Find the sum of the additive

inverse and multiplicative

inverse of 12. 20. Simplify 5/8+

9/2 X 5/2+ 5/8 pls answer soon ​

Answer 1

(1) First of all, we need to see the definition of Multiplicative and additive inverse.

• Multiplicative inverse of a certain number is a number which when multiplied gives 1, as the result.

• So, the multiplicative inverse can also be said to be the reciprocal of the number. 12 × 1/12 = 1

✤ Multiplicative inverse of 12 = 1/12 (Ans)

• Additive inverse of a certain number is a number which when added to it gives 0 as the result.

• So, the additive inverse is the same number with same value but opposite sign. 12 + (-12) = 0

✤ Additive inverse of 12 is -12 (Ans)

━━━━━━━━━━━

(2) To simplify : 5/8 × 9/2 + 5/2 × 5/8 (Correct Q.)

Taking 5/8 as common from both sides of '+'

➝ 5/8 (9/2 + 5/2)

➝ 5/8 (14/2)

➝ 5/8 (7)

➝ 35/8 (And)

The easier way of solving the above is based on distributive property of multiplication over addition.

And we are done $!!$

Answer 2

Answer:

Step-by-step explanation:

Additive inverse of 12 =-12

Multiplicative inverse of 12 is 1/12 then their sum is -143/12

(5/8+9/2)×5/2+5/8

205/16+5/8=215/16
