## How to calculate 10 percent of an amount

For averiguar el 10 por ciento de un número we only have to apply a simple rule of three: In this case, the two unknowns of which we do not yet know the value are the following:

• B: Número del cual queremos calcular su 10%
• Nos faltaría saber cuál es el valor de 'Y', número que representará el 10 por ciento del número inicial.

Applying the rule of three we can clear the value we are interested in as follows:

Y = quantity x 10 / 100 = quantity x 0.1

In short, to take 10 percent of something we have to multiply the number by 0.1. To make it clearer, we will now see how the above applies to a practical example.

## Calcular el 10 por ciento de 1000 Para averiguar el 10% del número 1000, vamos a utilizar la fórmula que hemos visto unas líneas más arriba:

Y =  = cantidad x 0,1 = 1000 x 0,1 = 100

As you can see, it is very easy calculate 10 percent of any number with a simple multiplication. Remember that multiplying by 0.1 is the same as dividing by 10, that is, you have to move the decimal point one place to the left. Surely this trick will allow you to calculate the percentage from memory and without the need for calculators.

## Calculate the 10 percent increase

So far we have seen how to calculate the 10% of an amount, but what if we want to calculate that percentage increase?

En ese caso lo único que tenemos que hacer es sumar a la cantidad inicial su 10%. Por ejemplo, vamos a calcular el 10 por ciento de aumento de 100:

10% increase = initial quantity x 0.1 + initial quantity = 100 x 0.1 + 100 = 110

## Calculate 10 percent less

If what we want is to subtract from a quantity its 10%, in that case the formula we will have to use will be the following:

For example, if we want to subtract 10% from 500, it would look like this:

500 - 500 x 0,1 = 500 - 50 = 450

Hi, I have a problem to solve. I would love it if you could help me.

In terms of probability, is it equally likely to hit a number out of 10 knowing that I have an 80% probability; and to hit a number out of 100 knowing that I have the same probability (80%).
Ex: I play a lottery number from 0 to 9 with an 80% probability of winning.
And I also play 1 number from 00 to 99, with an 80 % probability.
In which of the two options are you more likely to win?
It looks the same, but reportedly there is a slight difference.
Thank you very much

Hello,

As the number of elements in a set increases, the probability of drawing a particular one decreases.

For example, from 0 to 9, as there are 10 elements, the probabilities of drawing a specific one is 1/10 = 10%

However, in the example from 00 to 99 there are 100 elements and the probabilities are 1/100 = 1%.

As you can see, the difference is remarkable in one case and in the other. If in both cases you have a probability of 80%, you will have to calculate it on that 1% and 10% respectively.
