Write down the initial value, whether a decimal, fraction or percentage.
Multiply the initial value by the applicable conversion factor.
Convert a percentage to the equivalent fraction by placing the percentage as the numerator in a fraction whose denominator is 100. For example, 25 percent equals 25/100. Reduce the fraction if possible. The fraction 25/100 can be reduced to 1/4. Convert a percentage to the equivalent decimal by placing a decimal point two places to the left of the ones column of the percentage. For example, 25 percent would become 0.25, and 7 percent would become 0.07.
Convert a fraction to the equivalent percentage by dividing the numerator by the denominator and multiplying by 100. For the fraction 3/5, divide 3 by 5 to get 0.6. Multiply this by 100 to get 60 percent. Convert a fraction to the equivalent decimal by dividing the numerator by the denominator. The fraction 7/12 would become 0.583.
Convert a decimal to the equivalent fraction by counting the number of digits after the decimal point, then removing the decimal point and placing the number in the numerator. Write 1 in the denominator, followed by the same number of zeros as the number of places after the decimal. The decimal 0.555 would become 555/1000, which can be reduced to 111/200. Convert a decimal to the equivalent percentage by moving the decimal point two place values to the right. The decimal 0.849 would become 84.9 percent.
