Calculate Remember that percentages are based on one-hundredths. The value 100% is equal to 100 one-hundredths or 100/100. The v

alue 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:

75% = \frac{75}{100} = 0.75

20% = \frac{20}{100} = 0.20

0.8% = \frac{0.8}{100} = 0.008

Explanation:

75% means "75 for every 100". This can be represented as \frac{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 \frac{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 \frac{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.

If a trait would be advantageous to an organism, why hasn't it evolved?
dimulka [17.4K]
Because to actually use the word evolve an organism must suffice more than one condition, which in this case would be an advantageous trait. Having an advantageous trait (from our eyes at least) must also include the right and stimulating enviironment for procreation. So this answer is multifolded.
