Surely percents can always be expressed as fractions or decimals, but percents are useful for comparing values- percents are essentially fractions all of the same denominator so they are easier to compare.

Example: which is bigger 9/20 or 88/200 ?

which is bigger 45% or 44% ?

The percent question is easier to answer even though the numbers are the same.

What is 1 fourth of six percent?

no that's just 6 divided by 4 plus you cant divide a percent by a fraction unless you convert both into a decimal. the answer should be .24 because if you convert 1/4 into a decimal its .25 and 6% into a decimal is .06. When you divide .06 (the original 6%) by .25 (the original 1/4 fraction) you get the answer of .24

What is 36 percent as a fraction in its lowest term?

first you must change the percent to a decimal by moving the decimal point two places to the left: 36% --> 0.36then say the decimal out loud, so it would be easier to write the fraction: 0.36=thirty-six hundredthsnow, it is slightly easier to write the fraction: thirty-six hundredths= 36/100both are divisible by four so you do 36 divided by four (9) and 100 divided by four as well (25). now you cant simplify anymore, so 9/25 is your final answer.
