Question

5+(-7/2)+(-5/2)+(+19/9)​

Answer 1

Answer:

$5 + \frac{ - 7}{2} + \frac{ - 5}{2} + \frac{19}{9}$

$= > \frac{5}{1} + \frac{ - 7}{2} + \frac{ - 5}{2} + \frac{19}{9}$

$= > \frac{5 + ( - 7) + ( - 5) + 19}{18}$

$= > \frac{5 - 7 - 5 + 19}{18}$

$= > \frac{24 - 12}{18}$

$= > \frac{ \cancel12}{ \cancel18} = \frac{ \cancel6}{ \cancel9} = \frac{2}{3}$

$= > \frac{2}{3}$

Answer 2

Question:

$5+\frac{-7}{2} + \frac{-5}{2} + \frac{19}{9)}$

Answer:

$\implies \frac{5}{1} + \frac{ - 7}{2} + \frac{ - 5}{2} + \frac{19}{9}$

L.C.M of 1,2,2 & 9 = 18

$\implies \frac{5 + ( - 7) + ( - 5) + 19}{18}$

$\implies \frac{5 - 7 - 5 + 19}{18}$

$\implies \frac{24 - 12}{18}$

$\implies \frac{ \cancel12}{ \cancel18}$

$\implies \frac{ \cancel6}{ \cancel9}$

$\implies \frac{2}{3}$
