Problem: What is 35 percent of one dollar?
We know from the previous lesson that .35 = 35%. The word 'of' means multiply. So we get the following:
On the Home tab, in the Number group, click the percentage symbol to apply a Percentage format. Note: to change the percentage in cell A1, simply select cell A1 and type a new percentage (do not type a decimal number). Percentage of Total. To calculate the percentage of a total in Excel, execute the following steps. The shortcut way to convert from a percentage to a decimal is by removing the percent sign and moving the decimal point 2 places to the left. Express 50% as a decimal 'Percent' means 'per 100' or 'over 100'. So, to convert 50% to a decimal we rewrite 50 percent in terms of 'per 100' or over 100. 50% = 50 over 100. This calculator solves four types of percentage problems. Type 1: What is 15% of 20? This can be solved in two stps: Step 1: Write 15% as a decimal number: 15% = 0.15. Step 2: Multiply 0.15 and 20 to get the answer: 0.15. 20 = 3. Type 2: The number 25 is what percentage of 80? This can be solved in two stps: Step 1: Solve the equation: 80. x. To convert a percent to a fraction you first convert the percent to a decimal then use the same procedure as converting a decimal to fraction. How to Convert a Percent to Fraction. Divide the percentage by 100 to get a decimal number. Use that number as the numerator (top) of a fraction. Put a 1 in the denominator (bottom) of the fraction.
35% x $1.00 = .35 x $1.00

The solution to the above problem is not surprising, since percents, dollars and cents are all based on the number 100. To convert a percent to a decimal, first remove the percent symbol, then move the decimal point two places to the left. Look at the Example 1 below.
Example 1: Write each percent as a decimal: 18%, 7%, 82%, 55%
| Solution | |
| Percent | Decimal |
| 18% | .18 |
| 07% | .07 |
| 82% | .82 |
| 55% | .55 |
In Example 1, it was easy to convert each percent to a decimal since each percent had two digits. (The exception to this was 7% for which we needed to add in a zero in order to make the conversion.) Thus, we need a procedure to follow for consistency.
To write a percent as a decimal, follow these steps:
- Remove the percent symbol.
- Move the decimal point two places to the left, adding in zeros as needed.
Why do we move the decimal point 2 places to the left?
Remember that percent means parts per hundred, so 18% =
From your knowledge of decimal place value, you know that = 0.18 (eighteen hundredths).
Thus, 18% must also equal 0.18.
Let's take another look at Example 1, this time including the fractional equivalents of each percent.
Example 1: Write each percent as a decimal: 18%, 7%, 82%, 55%
| Solution | ||
| Percent | Fraction | Decimal |
| 18% | .18 | |
| 07% | .07 | |
| 82% | .82 | |
| 55% | .55 |
Let's look at another example of writing percents as decimals.
Example 2: Write each percent as a decimal: 12.5%, 89.19%, 39.2%, 71.935%
| Solution | |
| Percent | Decimal |
| 12.5% | .12500 |
| 89.19% | .89190 |
| 39.2% | .39200 |
| 71.935% | .71935 |
Summary: To write a percent as a decimal, remove the percent symbol, then move the decimal point two places to the left, adding in zeros as needed.

Simple and best practice solution for 2% of 63. Check how easy it is, and learn it for the future. Our solution is simple, and easy to understand, so don`t hesitate to use it as a solution of your homework.
If it's not what You are looking for type in the calculator fields your own values, and You will get the solution.
1. We assume, that the number 63 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 63 is 100%, so we can write it down as 63=100%.
4. We know, that x is 2% of the output value, so we can write it down as x=2%.
5. Now we have two simple equations:
1) 63=100%
2) x=2%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
63/x=100%/2%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for what is 2% of 63
63/x=100/2
(63/x)*x=(100/2)*x - we multiply both sides of the equation by x
63=50*x - we divide both sides of the equation by (50) to get x
63/50=x
1.26=x
x=1.26
now we have:
2% of 63=1.26
