The fraction of a whole number is a fundamental concept in mathematics that allows us to understand parts of a whole. To calculate 3/5 of 15, we can follow these simple steps:
- Divide the whole number by the denominator: First, we divide 15 by 5. The result is 3.
15 \div 5 = 3
- Multiply the answer by the numerator: Next, we multiply 3 by 3. The result is 9.
3 \times 3 = 9
Therefore, the answer to the question "What is 3/5 of 15?" is 9. This means that if we take one-fifth of 15, we get nine.
How to work with fractions
Fractions are formed by two parts: the numerator, which represents the number of parts, and the denominator, which represents the total number of parts in the whole. In the example of 3/5 of 15, the numerator is 3, and the denominator is 5, indicating that we have three parts of a whole that consists of five equal parts.
To solve more complex fractions, we can use various operations such as addition, subtraction, multiplication, and division. For instance, to add or subtract fractions, we need to find a common denominator. In the case of 3/5 and 5/7, we can find a common denominator by multiplying 5 by 7 to get 35. Then, we convert each fraction to have the same denominator and add or subtract the numerators as necessary.
Practice problems
Practice is key to mastering fractions. To improve your skills, try working through a variety of problems involving the fraction of a whole number. You can use fractions calculator tools to check your answers or create your own practice worksheets.
###Understanding how to work with fractions is essential for solving real-world problems in various fields, including medicine, engineering, and finance. By mastering the concept of fractions and practicing with different examples, you will be able to apply this knowledge to new challenges and situations.
