converting ratios to percentages calculator

Frequently, many people need to do percentage calculations involving money, as we see above.Bankrate follows a strict editorial policy, so you can trust that we’re putting your interests first. Notice ratios need not have only integer (whole number) parts. Why do the above two calculations have different results? 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 What is the percent the price dropped? (We would ask what is the 'discount?') We can easily flip the calculation on its head. 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.

If there are 145 questions on the test, how many do I have to get right to get an 'A'? Use Percentage Calculator 3 Or suppose we want to know what number 'X' is 90% of 'Y' if 'Y' is 145? (The ratio looks like this: X:145).What is the maximum amount the bill can be so that you'll still have enough to cover your share? Use Percentage Calculator 2 You have to pay 20% of an upcoming doctor's bill, and the insurance company will pay the balance. Imagine we want to know 'X' is 20% of what number 'Y' if 'X' equals 2,250.What happens when we know the percent, but we don't know one of the two numbers in the ratio? The balance of the material builds on what we've learned. If not, this would be a good place to stop and review what I've written so far. Notice also that percentage calculator 1 works as a percent to decimal calculator as well.ĭo you see the relationship between percents, ratios, and fractions? 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%. But for those who may have skipped ahead, the answer is simple. How? If you've been following along, you probably already know. Or you have 18.3% deducted from your pay.Ĭalculator 1 can also be used as a fraction to percent calculator. Enter 183 as 'This number' and the 1,000 as the 'is what percent of this number.' The result is 18.3%. 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. That is, it answers the question 'what percent is 'X' of 'Y', i.e., 'X:Y' or 'X/Y''? More belowĬalculator 1 converts any ratio to a percent. One thing first though, notice I DID NOT say the class is 80% boys. Can you figure out which of the below percent calculators I used to come up with this answer? If not, don't worry.

That is, the class has 80% the number of boys has it has girls.

We can say that the ratio 12:15 is the same as 80:100 or 80%. 'In terms of 100' means, if the right-hand side of the expression '12:15' (the '15') were actually '100' what number would we use to replace the '12' so we can still maintain the ratio of 12:15? A ratio is the same thing as a fraction it's just written out differently.Īlright, that's what a ratio is, but what does 'in terms of 100' mean? Wait a minute, that last thing is a fraction! (We could also say the ratio of girls to boys is 15:12.) And just an FYI, we could also write the ratio of boys to girls this way: 12/15. If a math class has 12 boys and 15 girls, we would say the ratio of boys to girls is 12:15. Well, a ratio is a relationship between two numbers. Percentages and Ratios (and Fractions too)
