Question

m.m.c a 7/2 + 3/2

b 4/3-7/6

c 5/6+1/9

d 1/2- 1/4
e 3/4-2/3


​

Answer 1

Resposta: a) $\frac{10}{2}$

b) $\frac{1}{6}$

c) $\frac{17}{18}$

d) $\frac{1}{4}$

e) $\frac{1}{12}$

Explicação passo a passo:

$a) \frac{7}{2} + \frac{3}{2} = \frac{10}{2}$

$b) \frac{4}{3} - \frac{7}{6} = \frac{8}{6} - \frac{7}{6} = \frac{1}{6}$        MMC: {3, 6} = 6

$\\c) \frac{5}{6} + \frac{1}{9} = \frac{15}{18} + \frac{2}{18} = \frac{17}{18}$    MMC: {6, 9} = 18

$\\d) \frac{1}{2} - \frac{1}{4} = \frac{2}{4} - \frac{1}{4} = \frac{1}{4}$        MMC:{2, 4} = 4

$e) \frac{3}{4} -\frac{2}{3} = \frac{9}{12} -\frac{8}{12} = \frac{1}{12}$    MMC:{4, 3} = 12
