Answer 1

a)

$\frac{7}{10} \times \frac{30}{49} + \frac{5}{7}$

$7 \times \frac{3}{9} + \frac{5}{7}$

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

$\frac{8}{7}$

b)

$\frac{5}{2} \times \frac{4}{25} + \frac{1}{5} \times \frac{1}{2}$

$\frac{2}{5} + \frac{1}{10}$

$\frac{1}{2}$

c)

$( \frac{7}{2} - \frac{5}{3} ) \times \frac{36}{55}$

$\frac{6}{5}$

d)

$\frac{2}{3} \times ((1 + 2) + ( \frac{1}{5} + \frac{1}{2} )) - \frac{13}{12}$

$\frac{2}{3} \times (3 + \frac{7}{10} ) - \frac{13}{12}$

$\frac{2}{3} \times 3 \frac{7}{10} - \frac{13}{12}$

$\frac{2}{3} \times \frac{37}{10} - \frac{13}{12}$

$\frac{1}{3} \times \frac{37}{5} - \frac{13}{12}$

$\frac{37}{15} - \frac{13}{12}$

$\frac{83}{60}$
