FutureStarr1 Out of 13 As a Percentage
ESPN found that 1 out of every 13 games in the postseason had a comeback victory by the home team from a 3- or 4-minute deficit.
To use it, first understand the ratio. For example, if you earn $1,000 a week and you have $183 taken out of your pay, and you want to know what percentage of your pay gets deducted from the total then the ratio you want to convert is 183:1000. Enter 183 as "This number" and the 1,000 as the "is what percent of this number." The result is 18.3%. Or you have 18.3% deducted from your pay.Calculator 1 can also be used as a fraction to percent calculator. How? If you've been following along, you probably already know. But for those who may have skipped ahead, the answer is simple. Take any fractions, for example, "27/82", and enter the numerator (27) into "This number." Then take the denominator (82) and enter it into "is what percent of this number." The percentage is 32.9268%.
Finally, what if you need to know the percentage change (increase or decrease) between amount or size "X" and "Y"? An item you have been thinking of purchasing had cost $249.95 and now costs $199.95. The ratio is 249.95:199.95. What is the percent the price dropped? (We would ask what is the "discount?") We can easily flip the calculation on its head. Suppose the price had been $199.95 and is now $249.95 (199.95:249.95), what is the percent increase? Use Percentage Calculator 4 (Source: financial-calculators.com)
Finding the difference in rates is more complex. In our second example, let’s assume that the country’s gross national product grew by 2%. This year, it grew by 2.5%, a change of 0.5 percentage points. This number seems unimpressive at first glance, but is it? Thus, we must look below the surface. How much did the percentages change? Let’s find the percentage change through the following formula:
); hence the net change is an overall decrease by x percent of x percent (the square of the original percent change when expressed as a decimal number). Thus, in the above example, after an increase and decrease of x = 10 percent, the final amount, $198, was 10% of 10%, or 1%, less than the initial amount of $200. The net change is the same for a decrease of x percent, followed by an increase of x percent; the final amount is p(1 - 0.01x)(1 + 0.01x) = p(1 − (0.01x) (Source: en.wikipedia.org)
