Respuesta:
a. 31 / 24
b. 5 / 21
c. 137,032
d. 77,48
Explicación paso a paso:
a.
5 / 8 + 4 / 6
= 5 / 8 + 2 / 3
= 15 / 24 + 16 / 24
= ( 15 + 16 ) / 24
= 31 / 24
b.
4 / 7 - 2 / 6
= 4 / 7 - 1 / 3
= 12 / 21 - 7 / 21
= ( 12 - 7 ) / 21
= 5 / 21
c.
28,125 + 35,486 + 73,421
= 63,611 + 73,421
= 137,032
d.
675,48 - 598
= 675,48 - 598,00
= 77,48
[tex] \frac{5}{8} + \frac{4}{6} = \frac{5}{8} + \frac{2}{3} = \frac{15}{24} + \frac{16}{24} = \frac{31}{24} [/tex]
en esta primera simplificamos 4/6 a 2/3 posteriormente se hace la operación en forma cruzada.
[tex] \frac{4}{7} - \frac{2}{6} = \frac{4}{7} - \frac{1}{3} = \frac{12}{21} - \frac{7}{21} = \frac{5}{21} [/tex]
nuevamente simplificamos 2/6= 1/3.
28.125+35.486+73.421= 137.032
675.48 - 598 = 77.48
