Answer 2

Opa! Bom dia.

a. $\frac{1+7}{10} \\\\\frac{8}{10} \\\\\frac{4}{5}$

b. $\frac{5-1}{6}\\\frac{4}{6} \\\\\frac{2}{3}$

c. $\frac{1+7-3}{10} \\\\\frac{5}{10}\\\\\frac{1}{2}$

d. $\frac{7-3-1}{15}\\\\\frac{3}{15}\\\\\frac{1}{5}$

e. $\frac{7+1+7}{20}\\\\\frac{15}{20} \\\\\frac{3}{4}$

f. $\frac{5+11-13}{18}\\\\\frac{3}{18} \\\\\frac{1}{6}$

g. $\frac{7+4-5+3-9}{6}\\\\\frac{0}{6} \\\\= 0$

h. $\frac{1+3+11-7}{20} \\\\\frac{8}{20} \\\\\frac{2}{5}$
