Answer 1

Resposta:

vou colocar tudo ali em baixo logo

Explicação passo-a-passo:

1

a)  $\frac{1}{2} + \frac{2}{3} = \frac{3 + 4}{6} = \frac{7}{6}$

b) $\frac{4}{5} + \frac{2}{3} = \frac{12+10}{15} = \frac{22}{15}$

c) $\frac{7}{8} - \frac{1}{6} = \frac{21 - 4}{24} = \frac{17}{24}$

d) $\frac{1}{2} - \frac{1}{3} = \frac{3 - 2}{6} = \frac{1}{6}$

e) $\frac{4}{5} - \frac{2}{7} = \frac{28 - 10}{35} = \frac{18}{35}$

f) $\frac{5}{6} + \frac{4}{6} = \frac{9}{6} = \frac{3}{2}$

g)$\frac{5}{4} - \frac{1}{2} = \frac{10-2}{4} = \frac{8}{4} = \frac{2}{1}$  

h) $\frac{8}{10} - \frac{1}{5} = \frac{8-2}{10}= \frac{6}{10}=\frac{3}{5}$

i) $\frac{2}{7} + \frac{1}{10} + \frac{3}{2} = \frac{20+7+38}{70} = \frac{65}{70} = \frac{13}{14}$

j) $\frac{4}{3} - \frac{4}{6} = \frac{8-4}{6} = \frac{4}{6} = \frac{2}{3}$

a) $\frac{5}{9} . \frac{7}{8} = \frac{35}{72}$

b) $\frac{3}{5} . \frac{3}{4} = \frac{9}{20}$

c) $\frac{1}{2} . \frac{1}{5} . \frac{1}{3} = \frac{1}{30}$

d) $\frac{3}{4} .\frac{1}{2} . \frac{3}{2} = \frac{9}{16}$

e) $\frac{2}{5} . \frac{5}{2} = \frac{10}{10} = \frac{1}{1}$

f) $(\frac{9}{10} )^{2} = \frac{9}{10} . \frac{9}{10} = \frac{81}{100}$

g) $\sqrt\frac{36}{64} = \frac{6}{8}$

h) $\sqrt\frac{49}{81} = \frac{7}{9}$

i) $\frac{3}{4} . \frac{1}{8} = \frac{3}{32}$

j) $\frac{4}{9} : \frac{6}{5} = \frac{4}{9} . \frac{5}{6} = \frac{20}{54}$

k) $(\frac{2}{5})^{3} = \frac{2}{5} . \frac{2}{5} . \frac{2}{5} = \frac{8}{125}$

l) $(\frac{2}{3}) ^{4} = \frac{2}{3} . \frac{2}{3} . \frac{2}{3} . \frac{2}{3} =\frac{16}{81}$

m) $(\frac{1}{3} ) ^{0} = 1$

n) $\sqrt \frac{9}{4} = \frac{3}{2}$

o) $\sqrt\frac{1}{100}=\frac{1}{10}$

p) $\sqrt\frac{100}{81} = \frac{10}{9}$
