Answer 1

a)

$\frac{6}{5} + \frac{8}{5} =$

$\frac{14}{5}$

b)

$\frac{4}{9} - \frac{2}{9} =$

$\frac{2}{9}$

c)

$\frac{7}{3} + \frac{3}{4} =$

$\frac{7}{3} + \frac{3}{4} = \frac{28 + 9}{12}$

$\frac{37}{12}$

d)

$\frac{5}{8} + \frac{1}{6} =$

$\frac{5}{8} + \frac{1}{6} = \frac{15 + 4}{24}$

$\frac{19}{24}$

e)

$\frac{3}{7} + \frac{2}{7} + \frac{13}{9} =$

$\frac{3}{7} + \frac{2}{7} = \frac{5}{7}$

$\frac{5}{7} + \frac{13}{9} =$

$\frac{5}{7} + \frac{13}{9} = \frac{45 + 91}{63}$

$\frac{136}{63}$

f)

$\frac{1}{2} + \frac{7}{4} - \frac{1}{4} =$

$\frac{1}{2} + \frac{7}{4} = \frac{9}{4}$

$\frac{9}{4} - \frac{1}{4} = \frac{9 - 1}{4}$

$\frac{8}{4}$
