Explicación paso a paso:

1. 1/5 x ( 1/2 + 1/3 ) =1. 1/5 x ( 1/2 + 1/3 ) =

$\frac{1}{5}$ x $\frac{5}{6}$ = $\frac{31}{30}$

2. ( 2/3 - 1/2 ) ÷ ( 1/3 - 1/5 )=

$\frac{1}{6}$ ÷ $\frac{2}{15}$ = $\frac{15}{12}$ = 1 $\frac{3}{12}$ = 1 $\frac{1}{4}$

3. 1/10 ÷ ( 2/3 - 3/5 ) =

$\frac{1}{10}$ ÷ $\frac{1}{15}$ = $\frac{15}{10}$ = 1 $\frac{5}{10}$ = 1 $\frac{1}{2}$

4. 7/4 ÷ ( 4/3 - 2/8 ) =

$\frac{7}{4}$ ÷ $\frac{26}{24}$ = $\frac{168}{104}$ = $\frac{84}{52}$ = $\frac{42}{26}$ = $\frac{21}{13}$ = 1 $\frac{8}{13}$

5. 5/3 – (2/5 x 7/2 ) =

$\frac{5}{3}$ - $\frac{14}{10}$ = $\frac{8}{30}$ = $\frac{4}{15}$

6. 5/6 + 13/8 - 5/12 =

$\frac{118}{48}$ - $\frac{5}{12}$ = $\frac{1176}{576}$ = 2 $\frac{24}{576}$ = 2 $\frac{2}{48}$ = 2 $\frac{1}{24}$

7. 2/3 + 4/9 - 3/5 =

$\frac{30}{27}$ - $\frac{3}{5}$ = $\frac{69}{135}$ = $\frac{23}{45}$

8. ( 5/6 + 5/4 ) x ( 7/10 - 1/4 ) =

$\frac{50}{24}$ x $\frac{18}{40}$ = $\frac{900}{960}$ = $\frac{90}{96}$ = $\frac{15}{16}$

9. 33/4 + 12/7 =

$\frac{279}{28}$

10. 3/10 ÷ ( 7/4 - 2/5 ) =

$\frac{3}{10}$ ÷ $\frac{27}{20}$ = $\frac{60}{270}$ = $\frac{6}{27}$
