Best Answer

Calculate the percentage for the numbers and then put the variables back in the answer.

For example,

20% of 36y = (20% of 36)*y = 7.2*y

or

25% of 36/y = (25% of 36)/y = 9/y.

You cannot. Percentage is a binary operator: you input two numbers and get one number as a percentage of the other or, equivalently, the percentage change from one to the other.

You can do all the calculations with variables - add the numbers, and divide by the size of the set. Of course, you'll probably end up having variables in the average as well.

The answer will depend on whether you want percentage equivalents of rational numbers or one rational number as a percentage of another.

/ The 2 numbers * By 100 and there is your answear!

In order to find the percentage increase and decrease between to numbers are easy. All you have to is subtract the number you start out with to the number it becomes.

It means that, by using the right numbers for the variables, you can simplify both sides of the equation and they will become the same number. But that is yourjob. You have to find those correct numbers for the variables. These are the anxwers for the problem.

Term- a number, a variable, or a product of numbers and variables.

To find the percentage of one number you divide the numbers then multiply the answer by 100. For an example, if you want to find the percentage of four that the number three is you divide three by four and then multiply the result ,which is 0.75, by 100 and your result or percentage would be 75%!

That depends on what the fractions, variables, and numbers are, on what the equation says, and on what you're asked to find. There's no general rule that's useful in every case. Sadly, there's no other choice but to use your brain every time.

It means to find what numbers the variables (the letters) must be in order to make the equation a true statement.
