Answer 2

Resposta:  a) 2  b) 3 c) $\frac{7}{6}$  d) $\frac{5}{6}$  e) $\frac{3}{4}$  f) $\frac{7}{12}$  g) $\frac{1}{12}$  h) $\frac{1}{15}$  i) $\frac{13}{7}$  j) $\frac{13}{72}$  k) $\frac{7}{2}$

Explicação passo a passo:

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

b) $\frac{4}{3} + \frac{5}{3} = \frac{9}{3} = \frac{3}{1} = 3$

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

d) $\frac{1}{2} + \frac{1}{3} = \frac{3 + 2}{6} = \frac{5}{6}$

e) $\frac{1}{2} + \frac{1}{4} = \frac{4 + 2}{8} = \frac{6}{8} = \frac{3}{4}$

f) $\frac{1}{3} + \frac{1}{4} = \frac{4 + 3}{12} = \frac{7}{12}$

g) $\frac{3}{4} - \frac{2}{3} = \frac{9 - 8}{12} = \frac{1}{12}$

h) $\frac{2}{5} - \frac{1}{3} = \frac{6 - 5}{15} = \frac{1}{15}$

i) $\frac{6}{4} - \frac{1}{7} + \frac{1}{2} = \frac{42 - 4 + 14}{28} = \frac{52}{28} = \frac{26}{14} = \frac{13}{7}$

j) $\frac{2}{9} + \frac{1}{8} - \frac{1}{6} = \frac{16 + 9 - 12 }{72} = \frac{13}{72}$

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