I think you are asking,"If 75% of a sum of money is £600, how do I find 100% of that mmoney?"

In this case notice that 75% is three quarters of £600,

There are many ways to solve the problem.

Because this is a simple case we could say, "If 75% of the amount required equals £600, another 25% would be a third of the 75% and a third of £600 is £200.

Add the £200 to the £600 and you have £800 for the answer.

If the figures are more difficult I would us another method: take this example:

If 85% of a sum of money is £425, how much is all of it?"

So , using 85% = 85/100 85/100 of £S = £425 So 1/100 of £S = £425/85

and 100 hundredths of £S will be (£425/85) * (£425/ 85) * 100 which is the same as saying $425 x 100/85; that means £425 multiplied by 100 over 85.

The answer is £500

Now 100 over 85 is the "upside down" figure for 85% which equals 85 over 100

In other words if 65% of £S is £39 how much is all of it.

Anmswer is found by multiplying £39 by the "upside down" of 65% which is 100 over 65 = £60

Take the number you have out of the whole, then dived it by the whole number. Multiply the resulting number by 100 and that's your percent.Example:What percentage is 7 of 10?7 / 10= .7.7 x 100 = 707 is 70% of 10.

To find a percentage in a whole number, multiply the number by 100%, or put two zeroes and a percent sign after the number.

a as a percentage of b = 100a/b

The answer depends on the percentage. In many real-life cases they are proper fractions and therefore cannot be converted to whole numbers.

Divide (the known part) by (the percent). The quotient is the whole unknown number.

To find a percentage in a whole number, multiply the number by 100%, or put two zeroes and a percent sign after the number.

You find the percentage equivalent and the round the result to the nearest whole number.

If you want to find x percent of a number y then you need to calculate y*(x/100). It makes no difference whether y is a whole number or not.

Divide 100 by the known percentage and multiply the result by the known part. This will calculate the whole. Example: £10 is equal to 25%. Thus the whole = (100/25) * 10 = £40.

====== Answer 1: ----------- proportion... A portion of the total is to its percentage of the total as the total is to 100%.

You have to carry out the multiplication and thentruncate the answer to find the lower whole number,add 1 to that to find the next whole number.
