# Percentages -- having trouble understanding how to take a percentage of a number

• zak100

## Homework Statement

What is 'a' divided by a% of a?

a div a/a * 100

## The Attempt at a Solution

a/1/a/a * 100 = a/100

which is not a correct answer. I can't define a%. In my view a% of a means 100 i.e. a/a * 100.

How would you express a% as a decimal number? Hint: what is 50% of something as a decimal number?

For a general value ##x##, what would be ##a\%## of ##x##? What would you get if you then put ##x = a##?

Hi,

a% of x = a/x * 100
if x = a , i would get 100.

I know about 50% as 0.5. I got this knowledge from the forum last time. But i don't know how to express a%, maybe 0.0a?

No, you have it wrong. 50% of 50 is one-half of 50, which is 25. 10% of 10 is one-tenth of ten, which is 1.

Hi,
<50% of 50 is one-half of 50>
= 0.5 (50)
what about a% of a = (a/100 )* a.
Is the above correct?
