How To Figure Percentages
How To Figure Percentages - Have you ever struggled with figuring out percentages? Well, you are not alone! It can be challenging at times but fear not, we have got your back. Below are four easy ways to calculate percentages, along with step-by-step instructions and tips to make things easier for you.
Method 1: Finding a Percentage of a Whole Number
Step 1:
Begin by writing the percentage you want to find as a fraction in the form of X/100.
For example, if you want to find out 30% of 50, you would write it as 30/100.
Step 2:
Next, multiply the fraction by the whole number you want to find the percentage of. In our example, it would be 30/100 x 50 = 15.
Therefore, 30% of 50 is 15.
Method 2: Finding the Percentage Increase
Step 1:
Subtract the original value from the new value. For example, if something goes from costing $50 to $60, you would subtract 50 from 60 to get 10.
Step 2:
Divide the difference you found in step 1 by the original value. Continuing from our previous example, we got 10 in step 1, so we would divide it by 50 to get 0.2.
Step 3:
Multiply the answer by 100 to get the percentage increase. So, 0.2 x 100 = 20%. Therefore, the percentage increase in this example is 20%.
Method 3: Finding the Percentage Decrease
Step 1:
Subtract the new value from the original value. For example, if something goes from costing $50 to $40, you would subtract 40 from 50 to get 10.
Step 2:
Divide the difference you found in step 1 by the original value. Continuing from our previous example, we got 10 in step 1, so we would divide it by 50 to get 0.2.
Step 3:
Multiply the answer by 100 to get the percentage decrease. So, 0.2 x 100 = 20%. Therefore, the percentage decrease in this example is 20%.
Method 4: Finding Percentage of a Part
Step 1:
Start by dividing the partial value by the total value. For example, if 2 apples cost $1 and you want to find the price of one apple, you would divide the $1 by 2 to get 0.5.
Step 2:
Multiply the answer from step 1 by 100 to get the percentage. So, 0.5 x 100 = 50%. Therefore, the price of one apple is 50% of $1, or $0.50.
These are the four easy ways to calculate percentages that can help you in a variety of situations. Remember to take your time and use these methods carefully to avoid any mistakes. Happy calculating!
