What is 3.6666 as a Fraction?

3.6666 as a fraction

 

Answer:

 

The answer for 3.6666 as a fraction will be 11/3.

 

Explanation:

 

Converting a repeating decimal to a fraction can be done by following these steps:

 

Step 1: Let x = 3.6666...

 

Step 2: Since the decimal repeats every four digits, multiply by 10,000 (10^4) to shift the decimal point: 10000x = 36666.6666...

 

Step 3: Subtract the original equation (x = 3.6666...) from this new equation: 10000x - x = 36666.6666... - 3.6666... 9999x = 36663

 

Step 4: Solve for x by dividing both sides by 9999: x = 36663/9999

 

Step 5: Simplify the fraction by dividing the numerator and the denominator by their GCD (3333): 36663/9999 = 11/3

 

Thus, 3.6666 can be written as a fraction 11/3.
