Question

Hola, me podrían ayudar por favor

Answer 1

Respuesta:

a) $\frac{3}{7}$

b) $\frac{6}{2} - 2 = \frac{6-4}{2} = \frac{2}{2} = 1$

c) $\frac{-12 + 7+2}{20} = \frac{-3}{20}$

d) $\frac{7}{6} - (\frac{10-3}{6} ) = \frac{7}{6} - \frac{7}{6} = 0$

e) $\frac{1}{35} - \frac{1}{28*7} = 7 * \frac{1}{35} - 7 * \frac{1}{28*7} = \frac{1}{5} - \frac{1}{28} = \frac{28-5}{140} = \frac{23}{140}$

f) $\frac{21-10}{36} = \frac{11}{36}$

g) $\frac{2}{5} - (\frac{8+15}{50}) = \frac{2}{5} - \frac{23}{50} = \frac{20-23}{50} = -\frac{3}{50}$

h) $\frac{49+144+18}{28} = \frac{211}{28}$
