Percentages are similar to fractions with an important difference. In fractions the whole is represented by the denominator (e.g. the number 5 in the fraction of 1/5) In percentages, the whole is represented by the number 100. In fact, "per cent" means "per 100" or "for each 100."
To solve the problem above, let’s convert it into equation form: 24 = __% x 120
In this example, the number 120 represents the whole and so, as a percentage, it would be equal to 100%. Written as a ratio, we would get: 100% : 120
If a student took a 120 question test and they got every answer correct, as a percentage they would get a 100% score on the test.
In our problem we have to discover what percentage 24 is out of a whole of 120. For now, let’s call this unknown percentage value "Y". Written as a ratio, we would get: Y% : 24
To see a relationship between these two ratios, let’s combine them into an equation: 100% : 120 = Y% : 24
It is critical that both of the % values should be on the same side of a ratio. For instance, if you decide to put the % value on the right side of a ratio, then the other % value should also be on the right side of its ratio.
"120 : 100% and 24 : Y%" is correct.
"120 : 100% and Y% : 24" is wrong.
Let’s solve the equation for Y by first rewriting it as: 100% / 120 = Y% / 24
Drop the percentage marks to simplify your calculations: 100 / 120 = Y / 24
Multiply both sides by 24 to isolate Y on the right side of the equation: 24 ( 100 / 120 ) = Y
Computing the left side, we get: 20 = Y
This leaves us with our final answer: 24 is 20% of 120
