NO. The word irrational means "cannot be expressed as a ratio". A fraction IS a ratio. For instance: in the ratio 1:3 , the total number of shares is 4(=1+3). The share 1 is 1/4 of the total. Since a fraction is a ratio, it is WRONG to say it is irrational, which would mean it is not a fraction (or ratio). However, it is also good to take note that even an irrational number is a real number.
