Assume the unknown value is 'Y'
100% / 40 = Y% / 16
100 / 40 = Y / 16
16 ( 100 / 40 ) = Y
40 = Y
Answer: 16 is 40 percent of 40
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: 16 = __% x 40
In this example, the number 40 represents the whole and so, as a percentage, it would be equal to 100%. Written as a ratio, we would get: 100% : 40
If a student took a 40 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 16 is out of a whole of 40. For now, let's call this unknown percentage value 'Y'. Written as a ratio, we would get: Y% : 16
To see a relationship between these two ratios, let's combine them into an equation: 100% : 40 = Y% : 16
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.
'40 : 100% and 16 : Y%' is correct.
'40 : 100% and Y% : 16' is wrong.
Let's solve the equation for Y by first rewriting it as: 100% / 40 = Y% / 16
Drop the percentage marks to simplify your calculations: 100 / 40 = Y / 16
Multiply both sides by 16 to isolate Y on the right side of the equation: 16 ( 100 / 40 ) = Y
Computing the left side, we get: 40 = Y
This leaves us with our final answer: 16 is 40 percent of 40
