Assume the unknown value is 'Y'

100% / 650 = 30% / Y

100 / 650 = 30 / Y

Y ( 100 / 650 ) = 30

Y = 30 ( 650 / 100 )

Y = 195

Answer: 30 percent of 650 is 195

What are percentages

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'.

How to solve

To solve the problem above, let's convert it into equation form: __ = 30% x 650

In this example, the number 650 represents the whole and so, as a percentage, it would be equal to 100%. Written as a ratio, we would get: 100% : 650

If a student took a 650 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 evaluate the 30 percent of 650. For now, let's call this unknown value 'Y'. Written as a ratio, we would get: 30% : Y

To see a relationship between these two ratios, let's combine them into an equation: 100% : 650 = 30% : Y

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.

'650 : 100% and Y : 30%' is correct.
'650 : 100% and 30% : Y' is wrong.

Let's solve the equation for Y by first rewriting it as: 100% / 650 = 30% / Y

Drop the percentage marks to simplify your calculations: 100 / 650 = 30 / Y

Multiply both sides by Y to transfer it on the left side of the equation: Y ( 100 / 650 ) = 30

To isolate Y, multiply both sides by 650 / 100, we will have: Y = 30 ( 650 / 100 )

Computing the right side, we get: Y = 195

This leaves us with our final answer: 30% of 650 is 195
