a) 4/5-2/7=
c)5/4-1/2=
b)7/8-1/6=
d)5/6-1/3=​

Answer 1

Resposta:

a) $\frac{4}{5} - \frac{2}{7} = \frac{28 - 10}{35} = \frac{18}{35}$

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

c) $\frac{7}{8} - \frac{1}{6} = \frac{42 - 8}{48} = \frac{34}{48} = \frac{17}{24}$

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