Question

Add -4/27 ,-3/7 & 2/-21​

Answer 1

Step-by-step explanation:

-4+27=23

-3+7=4

2+(-21)=-19

Answer 2

Answer:-

$\large\bf \red{ \frac{ - 4}{27} + \frac{( - 3)}{7} + \frac{2}{ - 21} }$

$= > \frac{ - 4}{27} + \frac{( - 3)}{7} + \frac{21}{2}$

Take L.C.M. of 27,7 and 2=2×3 ×3 ×3 ×7=378

$= > \frac{4}{27} \times \frac{14}{14} = \frac{56}{378}$

$= > \frac{ -3 }{7} \times \frac{54}{54} = \frac{ - 162}{378}$

$= > \frac{21}{2} \times \frac{189}{189} = \frac{3969}{378}$

$= > \frac{56 + ( - 162) + 3969}{378} = \frac{3863}{378}$
