Question

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%.

Answer 1

75% =
`(75)/(100)` = 0.75

20% =
`(20)/(100)` = 0.20

0.8% =
`(0.8)/(100)` = 0.008

Step-by-step explanation:

75% means "75 for every 100". This can be represented as
`(75)/(100)`. 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
`(20)/(100)`. 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
`(0.8)/(100)`. To convert to decimal, move the decimal place 2 spaces to the left: 0.8% would become 0.008

Hope this helps.
