Hallar el menor número no divisible por 4, 6, 9, 11 y 12, tal que al dividirlo por estos números se obtengan restos iguales.

Aloiza [94]

Answer:

397

Step-by-step explanation:

Sea 'p (x)' el número que no es divisible por 4, 6, 9, 11 y 12 de manera que cuando se divide por estos números da un resto igual, tenemos;

Por teorema del resto, tenemos;

p (x) = (x - a) · Q (x) + R

Dónde;

p (x) = El número, que se divide

Q (x) = El cociente

(x - a) = El divisor

R = El resto

Dado que el número más pequeño es 4, el resto, 0 <R <4

Para el número entero más pequeño arriba (x - a) · Q (x), tenemos;

R = 1

Observamos que el mínimo común múltiplo de 4, 6, 9, 11 y 12 = 396, por lo tanto, podemos tener;

(x - a) · Q (x) = 396

R = 1, dar;

p (x) = 396 + 1 = 397

Por lo tanto;

El número que no es divisible por 4, 6, 9, 11 y 12, de manera que cuando se divide por estos números da residuos iguales, p (x) = 397

An office has 80 employees, and 24 of the employees are managers. What percentage of the employees are managers?

andreyandreev [35.5K]

Solution:

30% of the employees are managers.

Explanation:

We have been given that there are 80 employees, and 24 of the employees are managers.

We have to find the percentage of the employees that are managers.

We can find this percentage with the below formula

$\% = \frac{\text{Number of managers}}{\text{Total number of employee}}\times 100$

On substituting the known values, we get

$\%=\frac{24}{80}\times 100\\\%=\frac{3}{10}\times 100\\\%=3\times 10\\\%=30\%$

Therefore, 30% of the employees are managers.
