Question

Resolva a seguinte expressão: F= 1/3 + 1/4 + 1/6 + 1/7.

Answer 1

Resposta:

MDC

3,4,6,7 /2

3,2,3,7 /2

3,1,3,7 /3

1,1,1,7 /7

1,1,1,1. /84

23/84+21/84+14/84+12/84=

44/84+14/84+12/84=

58/84+12/84=

70/84

Answer 2

Resposta:

F = 25/28

Explicação passo a passo:

mmc(3,4,6,7)

3,2², 2.3. 7

2².3.7 = 84

mmc(3,4,6,7) = 4.6.7 = 168

$\frac{1}{3} +\frac{1}{4}+\frac{1}{6}+\frac{1}{7}=\frac{28+21+14+12}{84} =\frac{75}{84} =\frac{25}{28}$
