.anyways...converting a percentage to a fraction is easy peasy. remember a percentage is just a number out of 100.......
What is the process for converting a percent to a fraction notation?
Such as 4½%(1 over 2) to a fraction notation.

What is the process of converting a fraction notation to a percent?
Such as 3 over 5 to a percent?

Please explain with detail because I am having a hard time understanding this.
Thank you!

Haha, i love it when people say "10 points!!!" and stuff like that :L...that is the reason we're on here...anyways...

converting a percentage to a fraction is easy peasy. remember a percentage is just a number out of 100.

so for you example we can say 4.5% = 4.5/100
but we don't like decimals in fractions so we can multiple both the top and bottom number by 2 to get:

9/200

for other cases such as 8%:

8/100 = 4/50 = 2/25, we keep making it smaller to simplify it, until we can no longer divide by 2 in this case. if you are allowed to use a calculator these are easy.

the process for converting fractions to percentage is even easier.

for your example, 3/5 means 3 divided by 5, so you just put that in a calculator if you are allowed one, and it will give you a decimal, then multiply that by 100 to get it as a percentage.

if you aren't allowed a calculator you have to multiply the top and bottom number by a number that will make the bottom 100.

so in this case if we multiply top and bottome by 20 we get 60/100

60 out of 100 is 60% as we learnt earlier.

hope this helped, if you need anymore help or don't understand anything feel free to drop us an email

a percent is a fraction,% means /100

4 and a half percent is:

4.5/100 since the numerator is a half double top and bottom.

9/200 looks about right.

So to convert a percent to a fraction put it over 100 and simplify.

The other way round is to do whatever it takes to the numerator to make the denominator into 100 then use the % sign instead of /100

hence 3/5, well to make 5 into 100 we have to multiply by 20 so let's multiply top and bottom by 20

3*20/5*20 = 60/100 or 60%

Hope this helps.

Just remember % means over 100 and you're laughing.

Hope this helps.

What is the process for converting a percent to a fraction notation?
Divide by 100. For example
10% = 10/100 = 1/10
What is the process of converting a fraction notation to a percent?
Multiply by 100 e.g
3/5 * 100 = 60%

Percent means PER " CENT"

CENT means 100

4 1/2 % = 4.5 /100 = 45/1000 = 9/200 ANSWER

b) 3/5

to convert to percentage just multiply by 100

3/5 X 100 = 300/5 = 60% ANSWER
