Question

How do u do percentage​

Answer 1

Answer:

Step-by-step explanation:

Ill try to break this down, simply:

When we talk about percentages we are talking about how much part of something we have and the percent sign is a just a symbol representing that.

Lets say we have 2 out of 10 apples and we need to convert this to a percentage

First think about how many apples we have in total... and that would be 10, and then how many apples we currently have being 2:

So if we put the part that we have over the whole thing we get:

$\frac{2}{10}$

So now lets turn this into a decimal, when its something over 10 its really easy, all we have to do is move the decimal back one place!

So we have 2 and if we move the decimal back one place we get .2 or 0.2

Now we have our decimal, to convert this into a percentage all we have to do is multiply our decimal by 100

So:

0.2 x 100 = 20%

All you do when you multiply by 100 is move the decimal back over 2 places one place for each zero so:

0.2 --> 2. --> 20.

Which gives us again 20%
