Question

O valor de (5¦0)+ (5¦1)+ (5¦2)+(5¦3)+(5¦4)+(5¦5)é: a. 2 b. 4 c. 8 d. 16 e. 32

Answer 1

Resposta:

O valor de (5 ÷ 0) + (5 ÷ 1) + (5 ÷ 2) + (5 ÷ 3) + (5 ÷ 4) + (5 ÷ 5) é $11\frac{5}{12}$.

Explicação passo a passo:

(5 ÷ 0) + (5 ÷ 1) + (5 ÷ 2) + (5 ÷ 3) + (5 ÷ 4) + (5 ÷ 5) =

= (0) + (5) + (5 ÷ 2) + (5 ÷ 3) + (5 ÷ 4) + (1) =

= 0 + 5 + (5 ÷ 2) + (5 ÷ 3) + (5 ÷ 4) + 1 =

= 5 + 1 + [(5 ÷ 2) + (5 ÷ 3) + (5 ÷ 4)] =

$= 6 + [(\frac{30}{12})+(\frac{20}{12})+(\frac{15}{12})]=\\= 6 + [\frac{30+20+15}{12}]=\\= 6 + \frac{65}{12}\\= \frac{72+65}{12}=\\=\frac{137}{12} =\\=11\frac{5}{12}$
