FutureStarrA Calculator With Percent Symbol
This calculator is for people who would like to calculate the percent symbol in their head. By entering the number of digits you wish the percent symbol to be, you can see what you would see on your calculator. You can also enter your number, inputting it as a decimal or fraction, then type in the percent symbol.
This is all nice, but we usually do not use percents just by themselves. Mostly, we want to answer how big is one number in relation to another number?. To try to visualize it, imagine that we have something everyone likes, for example, a large packet of cookies (or donuts or chocolates, whatever you prefer ðŸ˜‰ - we will stick to cookies). Let's try to find an answer to the question of what is 40% of 20? It is 40 hundredths of 20, so if we divided 20 cookies into 100 even parts (good luck with that!), 40 of those parts would be 40% of 20 cookies. Let's do the math:

Convert the percentage into decimal numbers. For example, to calculate the average of 30% of 50 and 20% of 80, we convert them into their decimal forms that are 0.3 and 0.2 respectively.Jenny converted the fraction 8/20 into an equivalent fraction 40/100 by multiplying the numerator and denominator with 5/5. As you enter the numbers for this calculation, you should notice that as soon as your hit the % button, your number of 15 converts to .15. The calculator will the proceed to calculate .15 x 75.32. Add percentages very directly. Because percentages all represent fractions with the common denominator of 100, you can add a list of percentages without any additional work. By contrast, remember that to add fractions, you must work through the steps of finding common denominators and converting your fractions to those common denominators. With percentages, however, no additional work is necessary.
0.225 is the fraction of staff that are managers, expressed as a decimal. To convert this number to a percentage, we need to multiply it by 100. Multiplying by 100 is the same as dividing by a hundred except you move the numbers the other way on the place values scale. So 0.225 becomes 22.5. The answer is that you convert the individual elements that make up the whole into a percentage. For example, if there had been 200 cells in the grid, each percentage (1%) would be two cells, and every cell would be half a percent.Consider the example above of 1/2, which we converted to the decimal of 0.5. To change this decimal to a percentage, shift the decimal point two spaces to the right. First rewrite 0.5 as 0.50. Then when you shift the decimal point two spaces, you turn 0.50 into the number 50%. (Source: www.wikihow.com)
