Answer 2

Using the rearrangement property,

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

Taking LCM,

$(\frac{13}{20} + \frac{14}{20}) + (\frac{11}{14} - \frac{10}{14})$

Adding everything,

$(\frac{27}{20} ) + (\frac{1}{14})$

LCM of 20 and 14 is 140

$(\frac{27*7}{20*7} ) + (\frac{1*10}{14*10})$

$(\frac{189}{140} + \frac{10}{140})$

$\frac{199}{140}$

= Answer is 199/140

Hope that answered your question.
