Change 239 to a common fraction or mixed number and express it in its simplest form
Evgen [1.6K]
If this is suppose to be 239%....

change to a fraction to look like this 238/100. This number cannot be reduced, so the common fraction is 239/100.

to make it a mixed number, you would simply divide 239 by 100. Your answer would come out to 2 with a remainder of 39. Put the remainder over the divisor and your answer for a mixed number will be 2 and 39/100.<span />
