Henry is working on building a dog house. He needs to get lumber that is 6 inches wide and 1.5 inches thick. He goes to the hardware store and sees that they have 6 by

In this concept, you will learn to convert decimals to mixed numbers.

### Converting Decimals to Mixed Numbers

Some decimal numbers represent both a part and a whole. These decimal numbers can be written as **mixed numbers**. The decimal number must have both a whole and a part to be written as a mixed number. The mixed number and the decimal are equal because they both have the same value.

Here is a decimal number.

Let’s write this decimal in a **place value** chart.

Tens |
Ones |
Decimal Point |
Tenths |
Hundredths |
Thousandths |
Ten-Thousandths |

4 | . | 5 |

This decimal number has 4 ones and 5 tenths. The 4 represents the wholes. The 5 tenths represents the fraction. The five is the numerator and the tenths is the denominator.

Next, check and see if the fraction can be simplified. In this case, five-tenths can be simplified to one-half.

A decimal value can only be expressed one way. However, many fractions can be written to express the same value.

Simplify

You can keep on creating equivalent fractions that have the same value as

Finding equivalent fractions for mixed numbers is similar. The whole number stays the same, but the fraction can vary.

Here is a decimal number.

Convert the decimal number to a mixed number and find equivalent fractions.

First, convert the decimal to a mixed number.

Then, simplify the fraction part of this mixed number to get another mixed number that is equivalent to the one above. The greatest common factor of 56 and 100 is 4.
