Associative Property of Rational Numbers

Add the follo...

Question

Add the following rational numbers:

(iii) $\frac{- 8}{11} and \frac{- 4}{11}$

Open in App

Solution

Given: $\frac{- 8}{11} and \frac{- 4}{11}$

$∴ \frac{- 8}{11} + \frac{- 4}{11} = \frac{- 8 + (- 4)}{11}$
$= \frac{- 8 - 4}{11}$
$= \frac{- 12}{11}$

Hence, the sum of $\frac{- 8}{11} and \frac{- 4}{11}$ is $\frac{- 12}{11}$
