Mixed Number To Improper Fraction - Conversion, Meaning, Examples

Mixed Number to Improper Fraction

In order to convert a mixed number to an improper fraction, we need to multiply the whole number with the denominator and then add this product with the numerator. This forms the new numerator of the improper fraction while the denominator remains the same. The mixed number to improper fraction conversion can be done easily with the help of a few steps discussed on this page.

Converting Mixed Number to Improper Fraction

Before learning how to convert a mixed number to an improper fraction, let us quickly go through the definition of mixed numbers and improper fractions. A mixed fraction is one whose value is always greater than 1 and it has a whole number part and a proper fraction. A mixed number example is \(3\dfrac{2}{5}\) is a mixed number. An improper fraction is one in which the numerator is always greater than or equal to the denominator. Some examples of improper fractions are 4/3, 7/3, 11/5, etc.

Let us understand the method of converting a mixed number to an improper fraction with the help of an example. Let us convert the mixed fraction \(7\dfrac{1}{5}\) to an improper traction using the following steps:

  • Step 1: Multiply the denominator with the whole number part. Here, 5 × 7 = 35.
  • Step 2: Add the numerator to the product obtained in step 1. So, we get, 35 + 1= 36.
  • Step 3: Write the value obtained in step 2 over the denominator. This will be the new numerator while the denominator will remain the same. So, \(7\dfrac{1}{5}\) = 36/5.

This is how we convert a mixed number to an improper fraction. Let us understand this with another example.

Example: Convert the mixed number to an improper fraction: \(2\dfrac{3}{4}\)

Solution: We can convert the mixed number to an improper fraction by using the following steps.

  • Step 1: Let us multiply the denominator with the whole number part. Here, we will multiply 4 by 2, that is, 4 × 2 = 8.
  • Step 2: Now, we will add this product to the numerator. This will be 8 + 3 = 11.
  • Step 3: So, 11 will be the new numerator while the denominator (4) will remain the same. This means, \(2\dfrac{3}{4}\) = 11/4.

Mixed Number to Improper Fraction

The other way to understand this process is the addition of the whole number part and the fractional part. For example, in the same example \(7\dfrac{1}{5}\), let us add the whole number (7) and the fraction (1/5). We get 7 + 1/5 = 7/1 + 1/5 = (35 + 1)/5 = 36/5. Therefore, this is another way to get the improper fraction from a mixed number.

How to Add Mixed Numbers to Improper Fractions?

In order to add mixed numbers to improper fractions, we first need to convert the mixed number to an improper fraction and then add them using the usual method of addition of fractions. If the given fractions are like fractions, then the addition can be done easily. However, if they are unlike fractions then they need to be converted to like fractions and then added. Let us understand this with the help of an example.

Example 1: Add \(3\dfrac{2}{5}\) + 14/5.

Solution: We will convert \(3\dfrac{2}{5}\) to an improper fraction which will be, 17/5. Now 17/5 + 14/5 = 31/5 = \(6\dfrac{1}{5}\). Therefore, the sum is \(6\dfrac{1}{5}\)

In case of unlike fractions, we need to find the Least Common Multiple (LCM) of the denominators and then convert them to like fractions. After this they can be added in the usual way.
