Percentages are defined as a fraction or portion of a whole. Generally percentages deal with an amount out of one hundred but can be used in sales, economics, and science. If you've walked into any store you're sure to find something marked a certain percent off. Fractions are not whole numbers with a numerator over a denominator. Usually the numerator and denominator are expressed as integers. There are four types of fractions: simple fractions, complex fractions, mixed fractions, and improper fractions. Decimals are also not integers. They are expressed often like 0.34 and are often rounded off since some go for too long. Both decimals and fractions are also used to convert to percentages.

According to the CDC, Oral Contraceptives have a failure rate of9%. Thus meaning their effectiveness is only 91%

90/100 x 210 = 9 x 21 = 189

20 percent of 365 is 73.

% rate = 26.67% = 4 /15 * 100% = 0.2667 * 100% = 26.67%

It should be 850%

Converting a number to a percent is easy; just multiply by 100: 0.0051 x 100 = 51 %

First, you must make sure that the denominators are the same, so ifyou are adding 3/6 + 4/8, you have to make the denominators thesame, but how? to make the denominators the same, you have to find the LCM, whichis the least common multiple, and in this case, 24 is the LCM, andso your fraction will...

Calculating concentration of a chemical solution is a basic skill all students of chemistry mustdevelop early in their studies. What is concentration?

Okay. The 'full amount' of something is one-hundred percent. Halfof one hundred is fifty. For example, if something costsfive-hundred dollars and it was on special in a shop, it would costtwo hundred and fifty dollars. So if an advertisement sayssomething is fifty percent off, it means half off the...

6.15 = 123/20

12/6 = 2.0

In order to solve something, there needs to be an equation. If I have read your equation right you have: (aÂ² - 4)/(2 + 6a) x (3 + 9a)/(aÂ² + 5a + 6) This looks like it needs to be simplified. There are two fractions being multiplied, so multiply thenumerators and denominators together,...

Theoretically forever, since there are an infinity of halvesmathematically. In actuality though, with words it gets ridiculous,because it's pointless to read half of a sentence, and you reallycan't read half of a word, or half of a letter, so eventually youwill read the whole thing. Looking at the...

A change from 320 to 380 would be an 18.75% increase

80 is 32% of 250.

You can put the percent number over 100 and multiply it by the number you want to decrease, like 9% decrease from 100 would be 9/100 times 100... If you have a calculator, you can move the decimal place over to the right twice, and mulitply. So 9% would be 0.09.
