Understanding Mixed Numbers and Improper Fractions
In mathematics, a mixed number is a combination of a whole number and a proper fraction. It is written in the form of a fraction with a whole number part and a fractional part. On the other hand, an improper fraction is a fraction where the numerator is greater than the denominator. In this article, we will learn how to convert a mixed number to an improper fraction.
The Problem: Converting $2 \frac{3}{19}$ to an Improper Fraction
The given mixed number is $2 \frac{3}{19}$. To convert this mixed number to an improper fraction, we need to multiply the whole number part by the denominator and then add the numerator. The result will be the new numerator of the improper fraction.
Step 1: Multiply the Whole Number Part by the Denominator
The whole number part is 2 and the denominator is 19. We multiply these two numbers together to get:
Step 2: Add the Numerator
The numerator of the mixed number is 3. We add this to the result of the multiplication:
Step 3: Write the Improper Fraction
Now that we have the new numerator, we can write the improper fraction. The denominator remains the same, which is 19. The new numerator is 41. Therefore, the improper fraction is:
Conclusion
In this article, we learned how to convert a mixed number to an improper fraction. We used the given mixed number $2 \frac{3}{19}$ as an example and followed the steps to convert it to an improper fraction. The result is $\frac{41}{19}$. This process can be applied to any mixed number to convert it to an improper fraction.
