Answer 2

Given :   $\dfrac{4}{7} +\dfrac{-8}{9} +\dfrac{-12}{7} +0 +\dfrac{16}{21}$

To Find: Evaluate the expression

Solution:

$\dfrac{4}{7} +\dfrac{-8}{9} +\dfrac{-12}{7} +0 +\dfrac{16}{21}$

Taking LCM = 63

$=\dfrac{36}{63} +\dfrac{-56}{63} +\dfrac{-108}{63} +0 +\dfrac{48}{63}$

As a + 0 = a   Hence

$=\dfrac{36}{63} +\dfrac{-56}{63} +\dfrac{-108}{63}+\dfrac{48}{63}$

$=\dfrac{36-56-108+48}{63}$

$=\dfrac{36-56-108+48}{63}$

$=\dfrac{ -80}{63}$

Hence

$\dfrac{4}{7} +\dfrac{-8}{9} +\dfrac{-12}{7} +0 +\dfrac{16}{21}$ $=\dfrac{ -80}{63}$
