In this post we learn how to convert decimal number into fraction.
After studying the concept we will move on to solve problems related to the concept
Decimal To Fraction
Suppose a decimal number is given to you
In order to convert it into fraction, follow the below step
Step 01
Insert 1 as denominator
Step 02
Count number of digits after decimal
In the below number, there are two digits after decimal
Step 03
Remove the decimal and insert two zeros in the denominator
Step 04
If possible, simplify (or reduce) the fraction
This is not possible in this case.
Hence we have converted decimal into fraction
1.53 ⟹ \frac{153}{100} \\\ \\
You can see that method is very simple and straight forward.
Let us see some other examples for conceptual clarity
Example 02
Convert 0.652 into fraction
Step 01
Insert 1 in denominator
Step 02
Count number of digits after decimal
You can see there are three numbers after decimal
Step 03
Remove the decimal and insert three zeros in denominator
Step 04
Further Simplify the fraction (if possible)
Hence the decimal 0.652 is converted into \frac{163}{25} \\\ \\
Example 03
Convert 0.000255 into fraction
Step 01
Insert 1 as denominator
Step 02
Count the number of digits after decimal
There are 6 digits after decimal
Step 03
Remove the decimal and insert six zeros in denominator
Step 04
Simplify the fraction as much as possible
Hence the decimal 0.000255 is converted into \frac{51}{200000} \\\ \\
Example 04
101.007 intro fraction
Step 01
Insert 1 as denominator
Step 02
Count number of digits after decimal
You can see there are three digits after decimal
Step 03
Remove the decimal and insert three zeros in denominator
Step 4
Further simplify the fraction (if possible)
Further simplification is not possible
Hence the decimal 101.007 is converted into \frac{101007}{1000} \\\ \\
Special Case of Recurring Number
Example 05
Find the fraction of recurring decimal
x = 0.3333 . . . . . . .
Step 01
Insert 1 in the denominator
Step 02
Multiply numerator and denominator by 3
As 0. 9999…. is very close to 1.
It can be assumed that 0.999.. = 1
Hence the fraction will be
