A percentage essentially means how much/many per 100. (100=cent, as in century, centimeter, or 100 cents to a dollar.)
To turn a fraction value into a percentage, simply multiply the numerator (top number) by the pecentage the denominator is out of 100. (Which is a simple matter of dividing 100 by the denominator. 100/5=20, thus 5 is 20% of 100.)
4 is 25 percent. 8 is 12.5 percent. 16 is 6.25 pecent.
So...5/8 = 5 x 12.5%= 62.5%
7/16 = 7 x 6.25%= 43.75%
5/4 = 5 x 25%= 125%

5/8 = .625 or 62.5%, 7/16 = .4375 or 43.75%, 5/4 = 1.25 or 125%.
To find this either use a calculator and divide the numerator (that's the top one) by the denominator (that's the bottom one.). It's that easy. Good Luck.

Look at it this way. 5 is to 8 as ??? is to 100. Sometimes it's written like this 5/8~x/100. The product of the outer numbers must equal the product of the inner numbers. So 5*100 = 8x. Do the division and you should have a nice percentage that is greater than 50% and less than 100%. Good enough?

Do you know how to cross-multiply? If so write:
5/8 = x/100
7/16 = x/100
5/4 = x/100
and solve for x.
The second for example would give you 7 times 100 = 16 times x
700 = 16x
x = 700/16 or 43.75 %

you divide them:then move the decimal over 2 places.
5 divided by 8=.40 =.625=62.5%
5 divided by 4= 1.25=125%
7 divided by 16= now u get the answer!!

take the 5 and divide it by 8 and you would get 62.5
the next one would be 7 divided by 16.
Good luck.

you only have to divide them and multiply by 100. add the % sign if needed. for example... 5 / 8 = 0.625 x 100 = 62.5%
It's really easy! Great luck with your homework ^-^
