Answer 1

Resposta:

Olá!

Explicação passo-a-passo:

a. $\frac{2}{3} +\frac{5}{6}-\frac{1}{2}$

$\frac{4+5-3}{6}$

$\frac{6}{6}=1$

b. $1-\frac{47}{100} -1+\frac{63}{100}$

$\frac{100-47-100+63}{100}$

$\frac{16}{100} =\frac{8}{50}=\frac{4}{25}$

c. $-\frac{47}{10}+2- \frac{175}{100} +\frac{148}{100}$

$\frac{-470+200-175+148}{100}$

$\frac{-297}{100}$

d.$\frac{3}{5} -(\frac{1}{2}+ \frac{3}{4}) +(\frac{1}{10}+ \frac{5}{8})$

$\frac{3}{5} -(\frac{2+3}{4}) +(\frac{4+25}{40})$

$\frac{3}{5}-\frac{5}{4}+\frac{29}{40}$

$\frac{24-50+29}{40}$

$\frac{3}{40}$

d.$-\frac{15}{6} -\frac{8}{2}$

$\frac{-15-24}{6}$

$\frac{-39}{6}=\frac{-13}{2}$
