Example Question #2 : How To Find Decimal Equivalent To A Percentage
Find the decimal equivalent to the percentage:
In order to find the decimal equivalent of a percentage, the number that makes up the percent has to be divided by 100. However, since it is division by a power of 10, we can accomplish the same thing, by moving the decimal point 2 places to the left, thus making the number smaller. For this problem, that looks like this:

Example Question #1 : Decimals And Percentage
If 20% of x is equal to 160% of y, then y is what percent of x?
12.5
800
125
8
1.25
12.5
We are told that 20% of x is equal to 160% of y. We need to write expressions for 20% of x and 160% of y and set them equal to one another.
In order to find an expression for 20% of x, we can write 20% as a decimal and multiply it by x. Since 20% = 0.20, we can write 20% of x as 0.2x.
Similarly, we can write 160% as 1.60y.
Now, we set these expressions equal to one another.
0.2x = 1.60y.
Since the question asks us to find y as a percentage of x, we need to solve for y in terms of x. Let's divide both sides of the equation by 1.60.
0.125x = y.
Therfore, y is equal to 0.125x, which is the same as 12.5% of x, since 12.5% expressed as a decimal is 0.125.
The answer is 12.5.
