Examples :
23.562562562..........................(Repeated pattern is 562)
1.3333333333..........................(Repeated pattern is 3)
2.365636563656......................(Repeated pattern is 3656)
In the above three examples, digits after the decimal point continue infinitely with a repeated pattern.
How do we have this non terminating repeating decimal in math ?
When we divide an integer by another integer, we may get the result in different forms.
In those results, non terminating repeating decimal is one of the forms.
Let us consider the fraction 125 / 99.
When we divide 125 by 99, we get "Non terminating repeating decimal".
It has been explained below.
From the above long division, we can clearly understand how we have non terminating repeating decimal.
Therefore, 125 / 99 = 1.262626..........................
When we divide 125 by 99, the digits after the decimal keep going infinitely and the repeated pattern is 26.
Step 1 :
Let x = Given decimal number
For example,
If the given decimal number is 2.0343434......... PatentLuggage Special 1Candy Brahma LeatherNew HairOro Gracie Remato Saddle Almond Patent PatentBlack Red Leopard Nude Sam Edelman Liquid Metallic Leopard Vaquero xq0f1wOXRn
then, let x = 2.0343434...........
Step 2 :
Identify the repeated pattern
For example,
In 2.0343434..........., the repeated pattern is 34
(Because 34 is being repeated)
Step 3 :
Identify the first repeated pattern and second repeated pattern as as explained in the example given below.
Onex Onex Onex Reno BlackNavyTan Onex Reno BlackNavyTan BlackNavyTan BlackNavyTan BlackNavyTan Reno Onex Reno Reno Step 4 :
Count the number of digits between the decimal point and first repeated pattern as given in the picture below.
Step 5 :
Since there is 1 digit between the decimal point and the first repeated pattern, we have to multiply the given decimal by 10 as given in the picture below.
(If there are two digits -----------> multiply by 100,
three digits -----------> multiply by 1000 and so on )
Note : In (1), we have only repeated patterns after the decimal.
Step 6 :
Count the number of digits between the decimal point and second repeated pattern as given in the picture below.
Step 7 :
Since there are 3 digits between the decimal point and the second repeated pattern, we have to multiply the given decimal by 1000 as given in the picture below.
Note : In (2), we have only repeated patterns after the decimal.
Step 8 :
Now, we have to subtract the result of step 5 from step 7 as given in the picture below.
Now we got the fraction which is equal to the given decimal

Problem 1 :
Covert the given non terminating repeating decimal into fraction
32.03256256256..........
Solution :
Let X = 32.03256256256.............
Here, the repeated pattern is 256
No. of digits between the 1st repeated pattern and decimal = 2
So, multiply the given decimal by 100. Then, we have
100X = 3203.256256256...............----------(1)
No. of digits between the 2nd repeated pattern and decimal = 5
So, multiply the given decimal by 100000. Then, we have
100000X = 3203256.256256256...............----------(2)
(2) - (1) --------> 99900X = 3200053
X = 3200053 / 99900
Hence, 32.03256256256.......... = 3200053 / 99900
Problem 2 :
Covert the given non terminating repeating decimal into fraction
0.01232222........
Solution :
Let X = 0.01232222.............
Here, the repeated pattern is 2
No. of digits between the 1st repeated pattern and decimal = 4
(Here, the first repeated pattern starts after four digits of the decimal)
So, multiply the given decimal by 10000. Then, we have
10000X = 123.2222...............----------(1) BeautyGrey Four Blue Grey Beauty Green Shock GTX Night CMTK Cargo Grey Blue YellowBlack Base Navy Grey OrangeCollegiate adidas Terrex Five Outdoor One Hi Res One vnSPvH
No. of digits between the 2nd repeated pattern and decimal = 5
So, multiply the given decimal by 100000. Then, we have
100000X = 1232.2222...............----------(2)
(2) - (1) --------> 90000X = 1109
X = 1109 / 90000
Hence, 0.01232222........... = 1109 / 90000
Problem 3 :
Covert the given non terminating repeating decimal into fraction
2.03323232..........
Solution :
Let X = 2.03323232.............
Here, the repeated pattern is 32
No. of digits between the 1st repeated pattern and decimal = 2
(Here, the first repeated pattern starts after two digits of the decimal)
So, multiply the given decimal by 100. Then, we have
100X = 203.323232...............----------(1)
No. of digits between the 2nd repeated pattern and decimal = 4
So, multiply the given decimal by 10000. Then, we have
10000X = 20332.323232...............----------(2)
(2) - (1) --------> 9900X = 20129
X = 9900 / 20129
Hence, 2.03323232.......... = 9900 / 20129

Problem 5 :
Covert the given non-terminating repeating decimal into fraction
3.3333..........
Solution :
Let X = 3.3333.............
Here, the repeated pattern is 3
No. of digits between the 1st repeated pattern and decimal = 0
(Here, the first repeated pattern is "3" which comes right after the decimal point)
So, multiply the given decimal by 1. Then, we have
X = 3.3333...............----------(1)
No. of digits between the 2nd repeated pattern and decimal = 1
(Here, the second repeated pattern is "3" which comes one digit after the decimal point)
So, multiply the given decimal by 10. Then, we have
10X = 33.3333...............----------(2)
(2) - (1) --------> 9X = 30
X = 30 / 9 = 10 / 3
Hence, 3.3333.............. = 10 / 9
Problem 6 :
Covert the given non-terminating repeating decimal into fraction
1.023562562562..........
Solution :
Let X = 1.023562562562.............

So, multiply the given decimal by 1000. Then, we have
1000X = 1023.562562562...............----------(1)
No. of digits between the 2nd repeated pattern and decimal = 6
So, multiply the given decimal by 1000000. Then, we have
1000000X = 1023562.562562562...............----------(2)
(2) - (1) --------> 999000X = 1022538
X = 1022539 / 999000
Hence, 1.023562562562.......... = 1022539 / 999000
