Calculate remember that percentages are based on one-hundredths. the value 100% is equal to 100 one-hundredths or 100/100. the value 50% equals 50/100, which can also be written as the decimal 0.50. the value 5% equals 5/100 or 0.05. the value 0.5% equals 0.5/100 or 5/1000 or 0.005. convert the following percentages into one-hundredths and then into a decimal: 75%, 20%, 0.8%.

75% = = 0.75

20% = = 0.20

0.8% = = 0.008

75% means "75 for every 100". This can be represented as . To convert to decimal, move the decimal place 2 spaces to the left: 75% would become 0.75

20% means "20 for every 100". This can be represented as . To convert to decimal, move the decimal place 2 spaces to the left: 20% would become 0.20

0.8% means "0.8 for every 100", but it's easier to understand if you write it as "8 for every 1000". This can be represented as . To convert to decimal, move the decimal place 2 spaces to the left: 0.8% would become 0.008
