What is a Mixed Number?
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. For example, is a mixed number where 2 is the whole number part and is the fractional part.
Why Convert Mixed Numbers to Improper Fractions?
Converting mixed numbers to improper fractions is an essential skill in mathematics, particularly in algebra and geometry. Improper fractions are easier to work with and can be used to simplify complex calculations. In this article, we will learn how to convert mixed numbers to improper fractions using a step-by-step approach.
Step 1: Multiply the Whole Number by the Denominator
To convert a mixed number to an improper fraction, we need to multiply the whole number part by the denominator of the fractional part. In the case of , we multiply 2 by 5.
2 × 5 = 10
Step 2: Add the Numerator
Next, we add the numerator of the fractional part to the product obtained in Step 1. In this case, we add 1 to 10.
10 + 1 = 11
Step 3: Write the Improper Fraction
Now that we have the numerator and the denominator, we can write the improper fraction. In this case, the improper fraction is .
The Final Answer
Therefore, the mixed number can be converted to an improper fraction as .
