Understanding the Concept of Converting Decimals to Fractions

To understand the concept of converting decimals to fractions, we need to know the place value of the decimal number.

The decimal number can be broken down into its place value, with the digits after the decimal point representing the tenths, hundredths, thousandths, and so on.

For example, the decimal number 3.2 can be broken down into its place value as follows:

3 (whole number)

• 0.2 (tenths)

The tenths can be further broken down into 2/10.

Therefore, 3.2 can be written as a fraction in simplest form as:

3 + 2/10 = 3 + 1/5 = 16/5

Step-by-Step Guide to Converting Decimals to Fractions

Here is a step-by-step guide to converting decimals to fractions:

1. Identify the decimal number to be converted.
2. Break down the decimal number into its place value.
3. Identify the tenths, hundredths, thousandths, and so on.
4. Write the tenths, hundredths, thousandths, and so on as fractions.
5. Add the fractions to the whole number.

For example, let's convert the decimal number 4.5 to a fraction:

1. Identify the decimal number: 4.5
2. Break down the decimal number into its place value: 4 (whole number)
   • 0.5 (tenths)
3. Write the tenths as a fraction: 5/10
4. Simplify the fraction: 1/2
5. Add the fraction to the whole number: 4 + 1/2 = 9/2

Therefore, the fraction in simplest form of 4.5 is 9/2.
