igor_vitrenko [27]

Answer:

30% members have voted.

Step-by-step explanation:

Given:

Number of members voted = 3

Number of members didn't vote = 7

We need to find what percentage of people voted.

Solution:

First we will find the total number of members in the election.

Now we can say that;

The total number of members in the election is equal to sum of Number of members voted and Number of members didn't vote.

framing in equation form we get;

The total number of members in the election = $7+3=10$

Now we will find the percentage of people voted.

So we can say that;

Percentage of members voted can be calculated by dividing Number of members voted from The total number of members in the election and then multiplying by 100 we get;

Percentage of members voted = $\frac{3}{10}\times100 = 30\%$

Hence 30% members have voted.

Answer:

Si estas pidiendo la respuesta a 1357 mas 5% de 1357 entonces la respuesta es 1,424.85.

Step-by-step explanation:

Para encontrar el % de cierto numero tienes que hagarar el numero como 5 y mover el decimal a la izquierda 2 veces entonces tendrias 0.05. Ahora multiplicas 0.05 por 1357 y tu respuesta seria 67.85. Y al final solo juntas 1357 y 67.85. Entonces 1357 + 67.85 = 1,424.85
