# How to Use Models to Divide Whole Numbers by Unit Fractions?

In this step-by-step guide, you will learn how to use models and visual shapes to divide whole numbers by unit fractions.

## Step-by-Step Guide Using Models to Divide Whole Numbers by Unit Fractions

A fraction contains a number with a denominator and a numerator.

To divide a whole number by a unit fraction, you have to follow these steps:**Step 1:** Place the whole number over the \(1\).**Step 2:** Flip the denominator and the numerator. It means \(1\) becomes a numerator and that whole number becomes the denominator.**Step 3:** Multiply the numbers.

**Using Models to Divide Whole Numbers by Unit Fractions – Examples 1**

Divide \(4÷\frac{1}{2}\). Use the models to help you.

#### Solution:

**Step 1:** Model the whole number \(4\).**Step 2:** Model \(\frac{1}{2}\) and find out how many fraction pieces makeup \(4\).**Step 3:** To make \(4\), it takes \(2\) of the fraction pieces. So, \(4÷\frac{1}{2}=8\).

**Using Models to Divide Whole Numbers by Unit Fractions – Examples 2**

Divide \(1÷\frac{1}{5}\). Use the models to help you.**Step 1:** Model the whole number \(1\).

Step 2: Model \(\frac{1}{5}\) and find out how many fraction pieces makeup \(1\).**Step 3:** To make \(1\), it takes \(5\) of the fraction pieces. So, \(1÷\frac{1}{5}=5\)
