ayúdenme porfa es de matemáticas doy muchos puntos

Answer 1

Respuesta:

a)

$\frac{5 + 3 + 2}{6} = \frac{10}{6} = \frac{5}{3}$

b)

$\frac{8 + 7 + 10}{4} = \frac{25}{4} = 6 \frac{1}{4}$

c)

$\frac{25}{20} + \frac{24}{20} + \frac{4}{20} = \frac{25 + 24 + 4}{20} = \frac{53}{20} = 2\frac{13}{20}$

d)

$\frac{70}{42} + \frac{48}{42} + \frac{147}{42} = \frac{265}{42} = 6 \frac{13}{42}$

e)

$\frac{13}{4} + \frac{13}{5} + \frac{5}{12} = \frac{195}{60} + \frac{156}{60} + \frac{25}{60} = \frac{195 + 156 + 25}{60} = \frac{376}{60} = 6 \frac{16}{60}$

f)

$\frac{23}{3} + \frac{22}{5} + \frac{31}{15} = \frac{115}{15} + \frac{66}{15} + \frac{31}{15} = \frac{115 + 66 + 31}{15} = \frac{212}{15} = 14 \frac{2}{15}$
