• #### How to find percentages leond429

I am stuck on turning a fraction Into a percentage on a calculator

Take your result, divide it by the total amount of marks and multiply by 100.

Hi leond429! If you want to convert a fraction into a percentage, simply multiply the fraction by 100. For example: 1/2 as a percentage is 1/2 × 100 = 50%.

Let's say you are given a question such as this: A shop keeper bought a TV for €500. He sold it for €600. What was the percentage profit?

This is what you do:

Final value - Original value

___________________________ × 100

Original value

So in this case you get:

€600 - €500

____________ × 100=

€500

20%

You can use this formula if you are dealing with percentage loss. Your percentage will be negative in that case.

Hope it helps :)

all you need to do is to multiply the fraction by 100. CathyR is right but he didn't understand it fully because he is converting the nominator of the fraction to a percentage. For example if a questions asks: "Convert 2/5 into a percentage". The answer is: 2/5 * 100 which is equal to 40%. BTW, * this means multiply.

hope this helps.

@hamzamughees I think you you were meaning to say "converting the denominator of the fraction to a percentage". Nominator is a different word altogether, and is unrelated to fractions! You do have the correct idea though. Remember: when a fraction is converted to a percentage, you are basically expressing the fraction differently, with 100 being the denominator. For example: 1/2 = 50/100. That is where the 50% originates. 50 percent is similar to saying 50 per 100.

OHHHH, Sorry, I actually meant numerator, but i got mixed up the numerator and nominator... LOL

Too long
