Question

Simplifique os resultados quando for possível:

A) 1/2 - 1/3=

B)5/6 - 1/3=

C)4/5 - 2/7=

D)7/8 - 1/6=

E)5/4 - 1/2=

F)8/10 - 1/5=

Answer 1

Resposta:

$a) \frac{1}{2} - \frac{1}{3} = \frac{3 - 2}{6} = \frac{1}{6} \\ \\ b) \frac{5}{6} - \frac{1}{3} = \frac{5 - 2}{6} = \frac{3}{6} = \frac{1}{2}$

$\\ \\ c) \frac{4}{5} - \frac{2}{7} = \frac{28 - 10}{35} = \frac{18}{35} \\ \\ d) \frac{7}{8} - \frac{1}{6} = \frac{21 - 4}{24} = \frac{17}{24}$

$\\ \\ e) \frac{5}{4} - \frac{1}{2} = \frac{5 - 2}{4} = \frac{3}{4}$

$f) \frac{8}{10} - \frac{1}{5} \\ \\ \: \: \: \: \: \: \frac{4}{5} - \frac{1}{5} \\ \\ \: \: \: \: \: \: \frac{4 - 1}{5} \\ \\ \: \: \: \: \: \: \frac{3}{5}$
