Converting Decimals to Fractions
The key point in this process is to know how to write the decimal as a mixed number. The rest is already a known procedure. Let's consider an example in this regard.
Example 5
Convert the following decimals into improper fractions.
a. 8.4
b. 5.03
c. 123.7
d. 76.008
Solution 5
- From theory, we know that the whole part of 8.4 is 8 and its decimal part is 4. In addition, the denominator of the corresponding mixed number is 10 because 8.4 has one decimal place. Hence, we have
8.4 = 8 4/10
When written as an improper fraction, this number becomes 8 4/10 = (8 × 10 + 4)/10 = 84/10
- From theory, we know that the whole part of 5.03 is 5 and its decimal part is 04. In addition, the denominator of the corresponding mixed number is 100 because 8.04 has two decimal places. Hence, we have
5.03 = 5 3/100
When written as an improper fraction, this number becomes 5 3/100 = (5 × 100 + 3)/100 = 503/100
- From theory, we know that the whole part of 123.7 is 123 and its decimal part is 7. In addition, the denominator of the corresponding mixed number is 10 because 123.7 has one decimal place. Hence, we have
123.7 = 123 7/10
When written as an improper fraction, this number becomes 123 7/10 = (123 × 10 + 7)/10 = 1237/10
- From theory, we know that the whole part of 76.008 is 76 and its decimal part is 008. In addition, the denominator of the corresponding mixed number is 1000 because 76.008 has three decimal places. Hence, we have
76.008 = 76 8/1000
When written as an improper fraction, this number becomes76 8/1000 = (76 × 1000 + 8)/1000 = 76008/1000
