Answer 1

2 1/3+ 3/15+7/2•10/14=35/15+3/15+70/28=38/15+70/28=2 8/15+2 14/28= 2 8/15+2 1/2=2 16/30+2 15/30=4 31/30=5 1/30

Answer 2

$\frac{21}{3} + \frac{1}{3} \times \frac{3}{5} + \frac{7}{2} \times \frac{10}{14}$

$\frac{21}{3} + \frac{1}{5} + \frac{5}{2}$

$\frac{210}{30} + \frac{6}{30} + \frac{75}{30}$

$\frac{291}{30} = \frac{97}{10}$
