Q1- Find the sum of additive inverse of ; and its multiplicative inverse. 1/2​

Answer 1

$\bf\purple{CorrecT~~QuestioN:-}$

Find the sum of additive inverse and multiplicative inverse of 1/2​

$\bf\red{AnsweR:-}$

• Additive inverse of 1/2 = -1/2

• Multiplicative inverse of 1/2 = 2

• The sum of both these numbers,

$:\implies\bf{\dfrac{-1}{2}+\dfrac{2}{1}}$

For finding this sum, at first we need to make the denominators same.

LCM[2, 1] = 2

$:\implies\bf{\dfrac{-1}{2}=\dfrac{-1}{2}}$ ----------- Eq.1

Here already denominator is 2 so no need of any step.

$:\implies\bf{\dfrac{2}{1}=\dfrac{2\times2}{1\times2}}$

$:\implies\bf{\dfrac{4}{2}}$ -------------- Eq.2

The sum of Eq.1 and Eq.2,

$\pink{:\implies\bf\dfrac{-1}{2}+\dfrac{4}{2}}$

$\pink{:\implies\bf\dfrac{-1+4}{2}}$

$\pink{:\implies\bf\dfrac{3}{2}}$

So, 3/2 is the required answer for your question!
