Introduction

In mathematics, converting divisions into mixed numbers is an essential skill that helps us express fractions in a more intuitive and user-friendly way. Mixed numbers are a combination of a whole number and a fraction, which can be more convenient to work with in certain situations. In this article, we will explore how to convert divisions into mixed numbers, using two examples to illustrate the process.

What are Mixed Numbers?

A mixed number is a combination of a whole number and a fraction. It is written in the form:

a b/c

where a is the whole number, b is the numerator, and c is the denominator. For example, 3 1/2 is a mixed number that represents 3 whole units and 1/2 of another unit.

Converting Divisions into Mixed Numbers

To convert a division into a mixed number, we need to follow these steps:

Divide the numerator by the denominator: This will give us a quotient and a remainder.
Write the quotient as the whole number: The quotient is the whole number part of the mixed number.
Write the remainder as the numerator: The remainder is the numerator of the fraction part of the mixed number.
Keep the denominator the same: The denominator remains the same as the original fraction.

Example 1: Converting 5 ÷ 9 into a Mixed Number

Let's start with the first example: 5 ÷ 9. To convert this division into a mixed number, we need to follow the steps above.

Step 1: Divide the numerator by the denominator

5 ÷ 9 = 0.5556 (repeating)

Step 2: Write the quotient as the whole number

The quotient is 0, which means we don't have any whole units.

Step 3: Write the remainder as the numerator

The remainder is 5, which is the numerator of the fraction part of the mixed number.

Step 4: Keep the denominator the same

The denominator remains 9.

The Mixed Number:

0 5/9

Example 2: Converting 28 ÷ 20 into a Mixed Number

Now, let's move on to the second example: 28 ÷ 20. To convert this division into a mixed number, we need to follow the same steps.

Step 1: Divide the numerator by the denominator

28 ÷ 20 = 1.4

Step 2: Write the quotient as the whole number

The quotient is 1, which means we have 1 whole unit.

Step 3: Write the remainder as the numerator

The remainder is 8, which is the numerator of the fraction part of the mixed number.

Step 4: Keep the denominator the same

The denominator remains 20.

The Mixed Number:

1 8/20

Simplifying the Mixed Number

In some cases, we may need to simplify the mixed number by finding the greatest common divisor (GCD) of the numerator and the denominator. The GCD is the largest number that divides both the numerator and the denominator without leaving a remainder.

For example, let's simplify the mixed number 1 8/20.

Step 1: Find the GCD of the numerator and the denominator

The GCD of 8 and 20 is 4.

Step 2: Divide the numerator and the denominator by the GCD

8 ÷ 4 = 2 20 ÷ 4 = 5

Step 3: Write the simplified mixed number

The simplified mixed number is 1 2/5.

Conclusion

Converting divisions into mixed numbers is an essential skill in mathematics that helps us express fractions in a more intuitive and user-friendly way. By following the steps outlined in this article, we can convert divisions into mixed numbers and simplify them when necessary. With practice, you will become more comfortable with converting divisions into mixed numbers and be able to apply this skill in a variety of mathematical contexts.
