Calculate: { \frac{2}{3}$}$ Of ${ 18\$} . What Is The Result?
Introduction
In mathematics, fractions are used to represent a part of a whole. When we are asked to calculate a fraction of a number, it means we need to find a part of that number based on the fraction given. In this article, we will learn how to calculate {\frac{2}{3}$}$ of ${18\$} and find the result.
Understanding Fractions
Fractions are written in the form {\frac{a}{b}$}$, where {a$}$ is the numerator and {b$}$ is the denominator. The numerator represents the number of equal parts we have, and the denominator represents the total number of parts the whole is divided into. For example, in the fraction {\frac{2}{3}$}$, the numerator is 2 and the denominator is 3.
Calculating a Fraction of a Number
To calculate a fraction of a number, we need to multiply the fraction by the number. In this case, we need to multiply {\frac{2}{3}$}$ by ${18\$}. To do this, we can use the following formula:
{\frac{a}{b} \times c = \frac{a \times c}{b}$}$
where {a$}$ is the numerator, {b$}$ is the denominator, and {c$}$ is the number we are multiplying by.
Applying the Formula
Now, let's apply the formula to our problem. We have {\frac{2}{3}$}$ and we need to multiply it by ${18\$}. Using the formula, we get:
{\frac{2}{3} \times 18 = \frac{2 \times 18}{3}$}$
Simplifying the Fraction
To simplify the fraction, we can divide the numerator and the denominator by their greatest common divisor (GCD). In this case, the GCD of 2 and 3 is 1, so we cannot simplify the fraction further.
Calculating the Result
Now, let's calculate the result of the multiplication:
{\frac{2 \times 18}{3} = \frac{36}{3}$}$
Final Result
To find the final result, we can divide the numerator by the denominator:
{\frac{36}{3} = 12$}$
Therefore, {\frac{2}{3}$}$ of ${18\$} is equal to ${12\$}.
Conclusion
In this article, we learned how to calculate {\frac{2}{3}$}$ of ${18\$} and find the result. We used the formula {\frac{a}{b} \times c = \frac{a \times c}{b}$}$ to multiply the fraction by the number, and then simplified the fraction to find the final result. We hope this article has helped you understand how to calculate fractions of numbers and find the results.

Introduction
Calculating fractions of numbers can be a challenging task, but with the right guidance, it can become a breeze. In this article, we will answer some of the most frequently asked questions about calculating fractions of numbers, providing you with a better understanding of this mathematical concept.
Q&A
Q: What is the formula for calculating a fraction of a number?
A: The formula for calculating a fraction of a number is {\frac{a}{b} \times c = \frac{a \times c}{b}$}$, where {a$}$ is the numerator, {b$}$ is the denominator, and {c$}$ is the number we are multiplying by.
Q: How do I simplify a fraction?
A: To simplify a fraction, divide the numerator and the denominator by their greatest common divisor (GCD). For example, if we have the fraction {\frac{12}{18}$}$, we can simplify it by dividing both the numerator and the denominator by 6, resulting in {\frac{2}{3}$}$.
Q: What is the result of {\frac{2}{3}$}$ of ${18\$}?
A: The result of {\frac{2}{3}$}$ of ${18\$} is ${12\$}. To find this result, we can multiply the fraction by the number using the formula {\frac{a}{b} \times c = \frac{a \times c}{b}$}$.
Q: How do I calculate a fraction of a decimal number?
A: To calculate a fraction of a decimal number, we can convert the decimal number to a fraction and then multiply it by the fraction. For example, if we want to calculate {\frac{1}{2}$}$ of ${3.5\$}, we can convert ${3.5\$} to a fraction by writing it as {\frac{7}{2}$}$ and then multiplying it by {\frac{1}{2}$}$.
Q: What is the difference between a fraction and a decimal?
A: A fraction is a way of expressing a part of a whole as a ratio of two numbers, while a decimal is a way of expressing a number as a sum of powers of 10. For example, the fraction {\frac{1}{2}$}$ is equal to the decimal ${0.5\$}.
Q: Can I use a calculator to calculate fractions of numbers?
A: Yes, you can use a calculator to calculate fractions of numbers. Most calculators have a fraction mode that allows you to enter fractions and perform calculations with them.
Q: How do I convert a fraction to a decimal?
A: To convert a fraction to a decimal, we can divide the numerator by the denominator. For example, if we have the fraction {\frac{1}{2}$}$, we can convert it to a decimal by dividing 1 by 2, resulting in ${0.5\$}.
Q: What is the result of {\frac{3}{4}$}$ of ${16\$}?
A: The result of {\frac{3}{4}$}$ of ${16\$} is ${12\$}. To find this result, we can multiply the fraction by the number using the formula {\frac{a}{b} \times c = \frac{a \times c}{b}$}$.
