Write 0.39 as a fraction in simplest form
nika2105 [10]
Here's how to convert 0.39 to a fraction...

There is not much that can be done to figure out how to write 0.39 as a fraction, except to literally use what the decimal portion of your number, the .39, means.

Since there are 2 digits in 39, the very last digit is the "100th" decimal place.

So we can just say that .39 is the same as 39/100.

So your final answer is: 0.39 can be written as the fraction 39/100 (ALREADY SIMPLIFIED)
