Answer 1

Resposta:

Explicação passo-a-passo:

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

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

c) $\frac{5+2}{6}$ = $\frac{7}{6}$

d) $\frac{3+2}{6}$ = $\frac{5}{6}$

e) $\frac{4+2}{8}$ = $\frac{6}{8}$

f) $\frac{3+4}{12}$ = $\frac{7}{12}$

g) $\frac{9-8}{12}$ = $\frac{1}{12}$

h) $\frac{6-5}{15}$ = $\frac{1}{15}$

i) $\frac{3+1}{2}$ - $\frac{1}{7}$ = $\frac{4}{2}$ - $\frac{1}{7}$ = $\frac{14-1}{7}$ = $\frac{13}{7}$

j) $\frac{16+19-12}{72}$ = $\frac{13}{72}$

k) $\frac{1+6}{2}$ = $\frac{7}{2}$
