How do I change a percentage to a fraction

How to convert percent to fraction

  1. Divide the percent by 100 to get decimal number.
  2. Count the number of digits (d) to the right of the decimal point of the decimal number.Example: 2.56 has 2 digits to the right of the decimal point, so d=2.
  3. Calculate the factor (f) for making the decimal number an integer: f = 10 to power d
    Example:
    f = 10 power 2 = 100
  4. Multiply and divide the decimal number x by the factor f: x * f / f = y / f
    Example:
    2.56 * 100 / 100 = 256 / 100
  5. Find the greatest common divisor (gcd) of the fraction. Example:
    gcd(256,100) = 4
  6. Reduce the fraction by dividing the numerator and denominator by the gcd value: Example:
    256 / 100 = (256/4) / (100/4) = 64/25
Example One percent is equal to one hundredth:
1% = 1/100
So in order to convert percent to fraction, divide the percent by 100% and reduce the fraction.
For example 56% is equal to 56/100 with gcd=4 is equal to 14/25:
56% = 56/100 = 14/25

My casio fx-82ms does not work when i use the 100% option ... example if i do 0.25 / 100% i would not give me the correct answer in stead of 25 it gives me o.25 .


100% is the same thing as 1, so .25 / 100% is the same as .25 / 1, which is 0.25 as the calculator shows. Why do you think it should be 25 and not 0.25?

I want to build a scale model of my house


o determine ANY scale you divide the actual measurement, in inches, millimeters, or miles, by the denominator in the fraction. for example:

25 inches in 1/25 scale is 1 inch. (you divide the 25 inches by the denominator in 1/25....25.) 25 divided by 25=1

IQ SOLVED 5*5=2030,3*5=1220,5*3=?


2012 is answer
(5) square = 25 , 25-5 = 20 , (5)square = 25 , 25+5 = 30 so == 2030, (3)square = 9 , 9+3 = 12, (5)square = 25 , 25-5 = 20 so == 1220, now
5) square = 25 ., 25-5 = 20, 3)square = 9 , 9+3 = 12


the +,-,+,- series is continued.

25 is 62.5% of 40 what are the step by step process


There are no unknowns in this question, but the step by step process for interpreting the words are:
1)' 25 is' means 25 =
2)' 62.5%' means 62.5/100, so 25 = 62.5/100
3)' of' means denominator of subject (which is the 25), so:
25/40 = 62.5/100.

This might be easier to see if there were an unknown. For example: 25 is what percent of 40? Using the above interpretation, this becomes:
25/40 = x/100 then solve for x.
Or, another example: 25 is 62.5% of what?
25/x = 62.5/100

How do I convert from decimals to fraction with my TI-30X IIS calculator? I need the step by step process


The following examples will demonstrate how to convert decimals into fractions using the TI-30Xa and TI-30Xa Solar. Please be aware that TI-30Xa Solar School Edition calculators do not have this functionality.

Example: Convert .25 to 1/4
- Input .25, press [2nd][<--] (says F<>D above it).

** F<>D means fraction to decimal, decimal to fraction.

Example: Convert 1.38 to 1_19/50

- Input 1.38, press [2nd][<--].

Example: Convert 9.75 to 9_3/4

- Input 9.75, press [2nd]{<--].
