9 Frequent Occasions Where Percentages Come In Handy

Percentages are utilized constantly, often unconsciously. Retail price reductions, rebates, and loan interest rates employ percentages. Just what is a share, to begin with?

Using this notation, a number may also be written as a fraction of 100. Thus, when we say something is 50%, we mean it is half of the whole. If we say it’s 75%, it translates to 12 out of 6500, or 3/4 of the total.

This basic idea of applied mathematics also helps us in several ways. Therefore, the paper’s emphasis will be the contexts in which we frequently encounter percentages and the methods for dealing with them. More information is also provided below.

1. The Formula for Tipping in Restaurants

Possibly twice a week, we go out shopping. Consequently, exchanging monetary value for tangible objects is universally accessible and understandable. There is also a strong emphasis on parental participation in this activity. Consider a hypothetical $50 meal bill as an example. If you want to tip, 20% is adequate. To calculate the gratuity, multiply your account balance by 0.2%. You save twenty percent or ten dollars.

2. Calculating the Right Tax Rate on Sales

Since sales tax is owed on all purchases, obtaining an estimate of the local rate is important. Adding the sales tax to a purchase price is also a great way to teach kids about this concept. For example, let’s pretend you need to buy a shirt that costs $25 but the local sales tax is 6%. The garment’s price also includes 0.06% sales tax. Thus, apparel must be taxed $1.50.

3. Determine Discounts

Just about anything these days can be had at a discounted price. In order to calculate your ultimate discount, you’ll need to know both the list price or original price of the item and the discount percentage. The total amount you’ll save is the List Price multiplied by the percentage you’re saving. For example, if a blouse usually costs $50 but is 20% off, you may calculate your savings by multiplying the original price by 0.2. Accurately, you may also expect to receive $10 (or 20% of $50). Therefore, the retail cost of the clothing is $40.

The following is the formula for calculating batting average in baseball and softball:

Only the cheeseburger rivals American baseball passion. Even young players can also compute their batting average. Average = hits/at-bats. Let’s pretend you’ve taken 400 swings and hit 100 times. If you want to know your batting average, bat 100 and divide by 400. To put it another way, your batting average would be 25%.

4. Final Exam Scores

Students should also be familiar with using percentages in this setting, as this is a typical occurrence. Knowing homework weights is also crucial. Percentage weight is also standard. To calculate how much of your final grade the exam determined, multiply your exam grade (0.8) by its importance in your total quality (. 0.30).

5. A Grounding in Inflation

Economists regard inflation as an important economic indicator. Economists calculate yearly, 5-year, and 10-year inflation rates using data and arithmetic. If tea leaves cost $5 in 2020 and $7.50 in 2022, inflation is 50%.

6. Energy Supplies

The “low battery” notification is a typical cause of frustration and downtime in our always-on society. However, in order to prevent power outages, all electronic devices have a battery percentage that can be monitored. All of our electronic devices, from phones to cameras to laptops, show us how much battery life they have remaining. Therefore, the ratio here aids in keeping tabs on the battery life.

7. Medicines

Percentage strengths of drugs are often printed on the back of the bottle or on the strip of pills. This ratio provides valuable information about the drug’s effectiveness. For this reason, it is normal practice in the medical industry to express results using percentages.

8. Survey Results and Conclusions

Statistics and percentages are common ways to portray survey results. You can quickly grasp the breakdown of these figures by using either a bar chart or a pie chart to display the data. This is being done so that we may have a deeper understanding of the study’s findings. Examples: 10% preferred Asian cuisine, 30% preferred Italian, 5% chose Mexican, 25% preferred fast food, and 30% chose healthier alternatives in a survey of 50 respondents.

9. Remarks on the Climate

Every country has its own meteorological office that releases forecasts for the next several days. Therefore, it’s essential that we can understand the information presented in weather reports from throughout the world. Predictions in such studies are also often shown as percentages. I’ll give you two examples: today, there’s a 20% chance of precipitation, and the humidity is at 70%. Therefore, there are many practical benefits to acquiring this knowledge.


Percentages are also used everywhere, from every day to the highly specialist. Enhance your analytical, deliberative, and communicative abilities while learning how to compute rates. Ratios are useful in many contexts, from adding a grade point average to determining the applicable sales tax. Make confident use of your acquired knowledge the next time you’re in a situation that calls for percentages!
