Common Uses Of Percentage In Our Daily Lives

We use percentages in our daily lives, often without even realizing it. The concept of a % is ubiquitous, appearing as discount percentages at stores, cash back on purchases, and interest rates on loans, just a few examples. I’m sorry, but could you explain what a percentage is?

Simply put, it’s a notation for writing numbers as fractions of 100. As a result, if we state that something is 50%, we indicate that it is half as likely as it is to be 100%. When we say “75%,” we mean 75 out of 100, or 3/4 of the way there.

It’s a fundamental principle of practical mathematics that streamlines our day-to-day existence. Therefore, the places and circumstances where we most frequently encounter percentages in our lives and how to handle them will be covered in this piece. Take a look at the details below.

Real-World Applications of Percentages

1.   In the context of a restaurant, figuring out how to appropriately tip your server

We frequent retail establishments because of the frequency with which we purchase for various necessities. Therefore, everyone can understand and relate to bartering money for goods. Parents are encouraged to participate in this exercise with their children. Now imagine you’re at a restaurant with a $50 bill. You should tip around 20%. Multiply the total amount of your bill by 0.2 to get the tip. You’ll receive $10, or 20% off your total.

2.   Determine the amount of tax due on a purchase

Sales tax is included in every purchase we make and is collected by law, so understanding it is crucial. Young people can learn about it by calculating “price of item + sales tax = total price” at a local store. To illustrate, say you want to buy a $25 blouse, but the local sales tax is 6%. Multiply the shirt’s price by 0.06 to estimate the tax. That shirt costs $20 after taxes of $1.50.

3.   Calculating prices for sales and coupons

Price reductions may be found on just about anything these days. You’ll need both the list price or original price of the item and the discount % to calculate your savings. List Price multiplied by Discount Percentage is Discount Amount. If a blouse costs typically $50 but is on sale for $20 off, you would multiply the original price by 0.2 to get the price after the reduction. That’s 20% off $50, or $10. Bringing the total for the garment to $40.

4.   During a baseball or softball game, your batting average is calculated by

If there’s one thing that the United States of America loves more than cheeseburgers, it’s baseball. Baseball is a sport played everywhere, and even young children can calculate their batting average. To determine this, we divide the number of hits by the total number of at-bats. Say, for argument’s sake, you have 100 hits in 400 at-bats. Simply divide 100 by 400 to get your batting average. You’d have a 25% batting average.

5.   Examining your academic report card

This is another common application of percentages that students should be familiar with. You can’t do that unless you know how much emphasis is placed on each type of assessment. Typically, the weight will be expressed as a percentage. If the final exam accounts for 30% of your mark and you earned an 80, you would multiply 0.8 by 0.30 to get your final score, which would be 24%.

6.   For a better grasp of inflation

Inflation is a central economic concept used by economists to determine the aggregate inflation of prices for goods and services over a specified period. Economists can report on price inflation over a year, five years, or ten years by tallying and calculating the prices and quantities. If a packet of tea leaves costs $5 in 2020 and $7.50 in 2022, then the price of tea has increased by 50% in just two years due to inflation.

7.   The power supply of the batteries

In a world where everyone is constantly connected to their gadgets, dead batteries are a common occurrence that can delay and impede productivity. However, to prevent devices from dying due to lack of juice, each one features a percentage of battery life that can be tracked. When we look at the percentage of a battery, we can see how much juice is left in our phones, cameras, and even our laptops. This percentage is helpful; it allows us to monitor the battery life.

8.   Pharmaceuticals

The percentage potency of a drug is typically listed on the back of a bottle of medicinal syrup or a strip of tablets. This percentage tells us how potent the medicine is, which is helpful on many levels. This is why percentages are commonplace in the medical field.

9.   Survey

The results of surveys are frequently presented in numerical form (usually as a percentage). The percentages accompanying these numbers on the bar graphs and pie charts make their presence clear. This is for the sole purpose of clarifying the findings of the research. In a sample of 50 people, for instance, 10% preferred Asian food, 30% for Italian, 5% for Mexican, 25% for fast food, and 30% for healthier options.

10.  Reports on the weather

We must be able to interpret weather reports as each country has its weather service that issues forecasts for the coming days. Estimates are typically presented as percentages in these types of reports. For instance, today, there is a 20% probability of precipitation and 70% humidity. Therefore, learning about these can aid us in numerous specific ways.
