Fractions to Percentages

The question on my math page reads :

Write each as a percent. Write remainders as a fraction.

The first 3 were easy because the denominator was a quotient of 100 (ex. 10, 20, 50). The one I'm having trouble with is the last :

64/128 (sixty-four over one hundred twenty-eight)

How do I make that a percentage? Please explain or show work, thanks in advance.

64/128=1/2=50/100=50%

You have to remember that 64/128 means 64 divided by 128.

So, simply make a division: 128 goes 0 times in 64 (0), add a zero (and it means you need to put your decimal, or dot there) 128 goes 5 times in 640 (0.5). So the percentage is 0.5 (or 50%)

What you can do, though, is make the division work as easy as possible, by bringing down the numerator and denominator as much as possible, so 64/128 = 32 / 64 = 16 / 32 = 8 / 16 = 4 / 8 = 2 / 4 = 1 / 2. Then, you can do it most times by mental math, with 1 / 2 = 0.5 (or 50%)

To turn a fraction into a percentage, simply simplify the fraction into a decimal the multiply by 100 and add the % symbol.

1/2=1 divided by 2 multiplied by 100%= 50%
3/4=3 divided by 4 multiplied by 100%= 75%
234/1000=234 divided by 1000 multiplied by 100%= 23.4%

64/128=64 divided by 128 multiplied by 100%= 50%

I hope you understand. :)
