A) 3/14+3/7
B) 3/5+3/4+2/2
C) 1/4+2/3+1/2​

Answer 1

Resposta:

a)

$\binom{63}{14}$

Explicação passo-a-passo:

$\binom{3}{14} + \binom{3}{7} = \binom{63}{14}$

b)

$\binom{3}{5} + \binom{3}{4} + \binom{2}{2} = \binom{35}{20}$

c)

$\binom{1}{4} + \binom{2}{3} + \binom{1}{2} = \binom{14}{12}$

Answer 2

Resposta:

Letra A)

$\frac{3}{14} + \frac{7}{7} = (tira \: o \: mmc \: de \: 14 \: e \: 7) \\ \frac{3 + 14}{14} = \frac{17}{14}$

Letra B)

$\frac{3}{5} + \frac{3}{4} + \frac{2}{2} = ( tira \: o \: mmc \: de \: 5 \: 4 \: e \: 2) \\ \frac{12 + 15 + 20}{20} = \frac{47}{20}$

Letra C)

$\frac{1}{4} + \frac{2}{3} + \frac{1}{2} = (tira \: o \: mmc \: de \: 4 \: 3 \: e \: 2) \\ \frac{3 + 8 + 6}{12} = \frac{17}{12}$
