As you can see in the title of this blog, I am going to be teaching anyone who doesn’t know how to calculate percentages without a calculator. I also have trouble doing these types of problems in my head. So, if you already know you can skip this, but if you don’t I highly encourage you to stay. This is something you will need if you want to go into business. Maybe you’re not, it’s a useful life skill nonetheless. I hope to see you at the end of this blog.

 First what is a percentage? A percentage is a fraction or a ratio in which the value of whole is always 100. For example, if I scored 30% in a math test, it means that I scored 30 questions out of 100. The following formula is commonly used to calculate the percentage of something. First determine the whole or total amount of what you want to find a percentage for. For example, if you want to calculate the percentage of how many days it snowed in a month, you would use the number of days in that month as the total amount. So, let’s say we are evaluating the amount of snow during the month of November, which has 30 days. As said in the last sentence, let’s say that it snowed 15 days out of the 30 days in November. You would divide 15 by 30, which equals 0.5. Then you would multiply 0.5 by 100. This equals 50, which would give you the answer of 50%. So, in November, it snowed 50% of the time. Another quick example, let’s say you put 400 dollars into a stock, and it went up 10%. You would have to multiply 10% to 400, and you get 40 which is one tenth of 400. Meaning you gained 40 dollars, and vise versa if it decreased 10%.

Now you know or I hope you do, how to find percentages in your head without a calculator. Thank you for sticking around until the end, hope you enjoyed. Over and out.
