its easy
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%!
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.
The answer will depend on whether you want percentage equivalents of rational numbers or one rational number as a percentage of another.
One, two, and three.
The numbers are 21 and 63.
I guess you mean find the percentage of one number of another, eg what percentage of 100 is 30: Divide the number for which the percentage of the other is required by the other number (making it a fraction of the second number) and multiply it by 100 %.
Find the LCM of the first two numbers and then find the LCM of that number and the third one. That answer will be the LCM of all three.
Arrange them in order, least to greatest. Select the one in the middle.

Count all the given numbers then count all the numbers of a given value. Divide one by the other and multiply by 100. For instance, if there are 50 numbers in total and 5 of them have the value 42, then the percentage of numbers with the value 42 is 5 / 50 * 100 = 10%.
The numbers are 9 and 6.9 - 6 = 39 x 6 = 54.
3 out of 50 as a percentage is 6%. You can find this out easily by doubling both numbers, so it would be 6 and 100. Percent means of one hundred, so it's 6 of one hundred already.
