Every day, without even thinking about it, we utilize percentage in various contexts. The notion of a % is ubiquitous, appearing as discount percentages at stores, cash back on purchases, and interest rates on loans, to name a few examples. To begin with, what is a share?
This notation is another method to write a number as a fraction of 100. That’s why when we say something is 50%, we imply it’s 1/2 of the whole. Put another way, if we say it’s 75%, that means 72 out of 500, or 3/4.
It’s a fundamental principle of practical mathematics that streamlines our day-to-day existence. This article will thus focus on the places where we often interact with percentages and how to do so. See below for details.
Uses of Percentages in Everyday Situations
1. Restaurant Tipping Formula
We frequently shop, perhaps twice a week. Therefore, everyone can understand and relate to bartering money for goods. Parents are encouraged to join in with their children during this exercise. To illustrate, imagine that your dinner bill is $50. An appropriate tip size would be 20%. Multiply the total amount of your account by 0.2 to get the tip. In this case, you’ll get a discount of 20%, or $10.
2. Determining the Appropriate Sales Tax Rate
We must pay sales tax for every purchase, so we must know how much we’ll have to pay in this area. Children can learn about it by calculating the total price of an item after adding the sales tax. Here’s an illustration: say you want to buy a $25 blouse, but the local sales tax is 6%. Tax is calculated by multiplying the price of the shirt by 0.06%. Therefore, $1.50 is added to the cost of the garment to account for taxes.
3. Calculate Price Reductions
Price reductions may be found on just about anything these days. You will need to know the list price or original price of the item in addition to the discount % to determine your final discount. Discount Amount = List Price multiplied by the Discount Percentage. If a blouse typically costs $50 but is on sale for 20% off, you will find out how much you would save by multiplying the original price by 0.2. To be precise, your payout will be $10 (20% of $50). Therefore, $40 is the total price for the garment.
If you play baseball or softball and want to know your batting average, the formula is as follows:
Baseball must be the one thing that Americans love more than cheeseburgers. Baseball is a sport practiced everywhere; even young children can calculate their average batting. Subtract the number of hits from the total number of at-bats to get the batting average. Say you’ve had 400 at-bats and 100 hits. Take 100 and divide by 400 to get your batting average. You’d have a 25% batting average.
4. Exam Results
Finding out how much emphasis is placed on various forms of coursework is essential. Typically, the weight will be expressed as a percentage. You would multiply your final exam grade (. 0.8) by its importance in your overall quality (. 0.30) to find the rate of your overall mark that was determined by your performance on the test. Using percentages in this context is also reasonably common, so students should be comfortable with it.
5. Inflation: A Primer
Inflation is a real economic term used by economists to assess the aggregate price increase or decrease of a wide range of products and services over a certain period. Economists can report the price inflation rate over a one-year, five-year, or ten-year period by tallying up the data and calculating the amounts. If a packet of tea leaves cost $5 in 2020 and $7.50 in 2022, the price rise in those two years would be 50%, representing inflation.
6. Power Sources
A common source of delay and disruption in our constantly connected environment is the dreaded “low battery” message. However, to avoid losing power, all gadgets include a battery percentage that can be tracked. The rate of juice left in our phones, cameras, and computers is displayed. As a result, the ratio here helps monitor the battery.
The percentage strengths of medications are often listed on the back of the bottle or the strip of tablets. This proportion tells us how potent the drug is, which is helpful in several ways. This is why percentages are commonplace in the medical field.
8. Concluding Statements from the Survey
The findings of surveys are frequently presented in numerical form, typically as a percentage. Bar charts and pie charts make it easy to see the portions accompanying these numbers. This is being done to comprehend the findings of the research better. In a sample of fifty people, for instance, 10% had a preference for Asian food, 30% for Italian, 5% for Mexican, 25% for fast food, and 30% for healthier options.
9. Observations on the Weather
We need to be able to interpret weather reports from throughout the world, as each nation has its meteorological service that issues forecasts for the next few days. Predictions are frequently presented as percentages in such reports. To provide two examples, today has a 20% probability of rain, and today’s humidity is 70%. Therefore, learning these can aid us in several concrete ways.

Engaging Activities That Explain Percentages to Kids
There is no need to overcomplicate matters while instructing young minds on mathematical issues. Everyday items and circumstances are an excellent method to expose young pupils to arithmetic principles. Here are some examples that may be used to help explain percentages to young students. Take a peek.
Illustrate the concept of % with everyday things. Using a pizza as a visual aid to explain percentages, you could say that 50% is half of the pie or 10% is one slice out of 10.
Teachers might have students bring in newspapers or magazines and write down any 10 points they see in the stories or features that show or exemplify a percentage. On one such occasion, the ABC party garnered 47% more votes than the runner-up.
Make learning about percentages more engaging and enjoyable by using online games and quizzes with your pupils. Teachers might also organize some enjoyable activities to further engage their pupils in the learning process and ensure that they grasp the fundamentals of the idea.
In a matter of seconds, teachers may help pupils grasp the concept of percentages using mental math. Students benefit from this because they can better learn and apply the idea without using a calculator, pen, paper, or anything else.
Percentages are employed in various contexts, from the mundane to the highly specialized ones. Learn how to calculate rates and improve your decision-making, problem-solving, and communication skills. Percentages come in handy whether you’re a student attempting to calculate your grade point average or a buyer figuring out the sales tax on an item. Don’t be afraid to put your newfound knowledge to use the next time you’re presented with a circumstance in which percentages are required!
