Answer: 15% of 30 is 4.5
Multiple methods of calculating percentage problems will help you find shortcuts for solving any percentage deduction problem. Here we have shown more than three different ways to subtract the actual percentage value from the main value. As a result, it gives you a comprehensive understanding of a defined percentage of the main value and provides you with different procedures that you can use to calculate any specified percentage of any value in the future.
A pie chart depicting fifteen percent of three hundred
A pie chart depicting 15% of 30 is shown below. The total pie has 30 parts (one side), and the small part of the pie is 4.5 parts, or 15 percent of 30, which was subtracted (other side).
It’s worth noting that the parts don’t have to be the same. It could be 15 percent of 30 of anything such as liquids, powders, shares, things, people, money, animals, or something similar. Whatever the percentage is, 15% of the pie chart (30 parts) will appear the same.
Calculate what is 15 percent of 30.
We already have our total value/main value, as well as our percentage value, which we should use to subtract an unknown value from the main value. So, assume that the unknown value is Y, which answer we will find out using a series of steps.
It can be subtracted using one of the following equations:
(Absolute value × Percent value)/100 = Part
(Absolute value × 100)/Percent value = Part
Incorporate the values using one of the above equations.
(30 × 15)/100% = 450/100 = 4.5
(15/100%) × 30 = 0.15 × 30 = 4.5
What is 15 percent of 30?
The part is subtracted from the main value in the step-by-step procedure.
Now we need to calculate 15% of 30, as explained in the procedure.
Step 1: In this case, the absolute value is 30.
Step 2: Assume that the value of y in the below equation is unknown.
Step 3: Assume that the value of 30 is 100 percent.
Step 4: In the same way, y = 15%.
We now have two equations as a result of these steps.
Equation 1: 30 = 100%
Equation 2: y = 15%
Step 5: Divide equation 1 by equation 2 and note that both equations’ RHS (right-hand sides) have the same unit (%).
30/y = 100%/15%.
Step 6: Finally, the reciprocal of both sides results in
y/30 = 15% /100%
As a result, y= 4.5
Therefore, 15% of 30 is 4.5
Simple methods to get the answer to this question?
There are two simple ways through which you can get an exact answer to any percentage problem. In the first method, divide both the percent value of 15 and the main value of 30 by 4.5 to get their decimal or single-digit values. To get the final value, multiply them together (1.5 * 3.0) as shown in the diagram.
In the second method, divide only one of these values (30 or 15) by 100 and multiply them together to get the actual answer.
How do you find 15 percent of 30 in a simple way?
When you multiply both 0.15 and 30 together, you get 4.5, which is 15% of 30.
The 0.15 represents 15%, which is obtained by dividing the 15 by 100 (15/100=0.15).
Dividing the percent (15%) by 100 and multiplying by the main number (30) is the simplest way to solve this problem. To get 0.15, divide 15 by 100. From there, multiply the decimal form of a percent (0.15) by 30 to get 4.5.
