Resource summary

Fractions, Decimals and Percentages
1 Fractions to decimals
1.1 Times or divide the fraction until the denominator is 10,100 or 1000. the last digit of the nominator will be in either the tenth, hundredth or thousandth depending on the denominator.
1.1.1 e.g. 126/200 divided by 2 = 63/100 = 0.63
2 Fractions to percentages
2.1 Times the fraction until the denominator is 100. The nominator is the percentage.
2.1.1 e.g. 5/10 times 10 = 50/100 = 50%
3 Decimals to percentages
3.1 With a decimal the last digit has to be in the hundredth column. If the last digit is in the tenth column add a zero on the end, if the last digit is past the hundredth column the percentage is a decimal percentage.
3.1.1 e.g. if the decimal is 0.75 the percentage is 75%. If the decimal is 0.2 you change it to 0.20 which means the percentage is 20%. If the decimal is 0.275 the percentage would be 27% but do not forget the extra digit meaning that the percentage is 27.5%
