How do you change 0.16666 in a fraction
Natasha_Volkova [10]
Here's how to convert 0.16666 to a fraction...

There is not much that can be done to figure out how to write 0.16666 as a fraction, except to literally use what the decimal portion of your number, the .16666, means.

Since there are 5 digits in 16666, the very last digit is the "100000th" decimal place.

So we can just say that .16666 is the same as 16666/100000.

The fraction 16666/100000 is not reduced to lowest terms. We can reduce this fraction to lowest
terms by dividing both the numerator and denominator by 2.

Why divide by 2? 2 is the Greatest Common Divisor (GCD)
or Greatest Common Factor (GCF) of the numbers 16666 and 100000.
So, this fraction reduced to lowest terms is 8333/50000

So your final answer is: 0.16666 can be written as the fraction 8333/50000
