Question

-13/20+11/14+-5/7+7/10

Answer 1

-13/20 + 7/10 =-13 +14 /20 =1/20
11/14 - 5/7 =11-10/14 =1/14
1/20 + 1/14 =14+20/280
=34/280
=17/140

Answer 2

Hi mate,


Here is your answer


$\frac{ - 13}{20} + \frac{11}{14} + \frac{ - 5}{7} + \frac{7}{10}$

NOW WE FIND THE L.C.M. of 20,14,7,10

so L.C.M. of 20,14,7,and 10 is 140


$= \frac{ - 91 + 110 - 100 +98 }{140}$


$= \frac{17}{140}$

HOPE THIS IS HELPFUL FOR YOU
