WHAT IS 15 OF 90: Everything You Need to Know
What is 15 of 90 is a mathematical problem that involves division and understanding the concept of fractions. In this comprehensive guide, we will break down the steps to solve this problem and provide practical information to help you understand the concept.
Understanding the Concept of Fractions
Fractions are used to represent a part of a whole. They consist of a numerator (the top number) and a denominator (the bottom number). The numerator represents the number of equal parts we have, while the denominator represents the total number of parts the whole is divided into. To solve a problem like 15 of 90, we need to understand that it's asking us to find what fraction of the whole is 15. One way to approach this problem is to think of it as a part-to-whole relationship. Imagine you have a pizza that is divided into 90 equal slices. If you eat 15 of those slices, you're eating a certain proportion of the whole pizza. This proportion is what we're trying to find.Breaking Down the Problem into Steps
To solve 15 of 90, we need to follow these steps:- Divide the numerator (15) by the denominator (90) to find the fraction.
- Reduce the fraction to its simplest form, if possible.
- Express the fraction as a decimal or percentage, if required.
Step 1: Dividing the Numerator by the Denominator
To divide 15 by 90, we need to perform long division. We can also use a calculator or a online tool to make the process easier. Here's the calculation:| Division | Result |
|---|---|
| 15 ÷ 90 | 0.1667 |
The result of the division is 0.1667.
Step 2: Reducing the Fraction to its Simplest Form
To reduce the fraction, we need to find the greatest common divisor (GCD) of the numerator and denominator. In this case, the GCD of 15 and 90 is 15. We can reduce the fraction by dividing both the numerator and denominator by the GCD:| Reducing the Fraction | Result |
|---|---|
| (15 ÷ 15) / (90 ÷ 15) | 1/6 |
The reduced fraction is 1/6.
Step 3: Expressing the Fraction as a Decimal or Percentage
We can express the fraction 1/6 as a decimal by dividing the numerator by the denominator:| Decimal Form | Result |
|---|---|
| 1 ÷ 6 | 0.1667 |
We can also express the fraction as a percentage by multiplying the decimal form by 100:
| Percentage Form | Result |
|---|---|
| 0.1667 × 100 | 16.67% |
The final answer to the problem 15 of 90 is 1/6, which can also be expressed as 0.1667 as a decimal or 16.67% as a percentage.
Practical Applications of the Concept
The concept of fractions is used in various real-world applications, such as:- Cooking and recipes: Fractions are used to measure ingredients and proportions in recipes.
- Science and math education: Fractions are used to represent proportions and ratios in various scientific and mathematical concepts.
- Finance and economics: Fractions are used to represent interest rates, inflation rates, and other economic concepts.
In conclusion, understanding the concept of fractions and following the steps outlined in this guide will help you solve problems like 15 of 90. Remember to reduce the fraction to its simplest form and express it as a decimal or percentage, as required.
