Answer 1

Resposta:

Explicação passo-a-passo:

a) $\frac{7}{9}$ + $\frac{1}{4}$ = $\frac{28+9}{36}$ = $\frac{37}{36}$

b)$\frac{7}{4} - \frac{1}{8} + \frac{5}{6}$ = $\frac{42-3+20}{24}$= $\frac{19}{24}$

c)$\frac{3}{8} +\frac{1}{10} - \frac{2}{5}$= $\frac{15+4-16}{40}$= $\frac{3}{40}$

d)$\frac{5}{6} + \frac{10}{4}$= $\frac{10+30}{12}$= $\frac{40}{12}$= $\frac{10}{3}$

e)$\frac{9}{4} - \frac{5}{6} = \frac{27-10}{12} = \frac{17}{12}$

f)$\frac{8}{9} - \frac{1}{4} + \frac{5}{6} = \frac{32-9+30}{36} = \frac{53}{36}$

g)$\frac{3}{4} + \frac{1}{10} - \frac{5}{6} = \frac{45+6-50}{60} = \frac{1}{60}$

h)$\frac{3}{5} + \frac{1}{4} - \frac{4}{6} = \frac{36+15-40}{60} = \frac{11}{60}$
