Question

Find the sum of 5/2, multiplicative identity of rational number and additive inverse of
-3/4​

Answer 1

Answer:

$\: \: \sf \: the \: answer \: is \: \frac{13}{6}$

step by step explanation:

Multiplicative identity of rational number is 1.

Additive identity of rational number is 0.

Let x be the additive inverse of -$\dfrac{2}{3}$

$\: \: \sf \: - \frac{2}{3} + x = 0 \\ \\ \: \: \sf \: x = \frac{2}{3}$

The sum of 1/2, multiplicative identity of rational number and additive inverse of -2/3.

$\: \: \sf \: \frac{1}{2} + 1 + \frac{2}{3} \\ \\ \: \: \sf \: \frac{3 + 6 + 4}{6} \\ \\ \: \: \sf \: = \frac{13}{6}$

Hence, the number is 13/6.
