To write 0.233 as a fraction you have to write 0.233 as numerator and put 1 as the denominator. Now you multiply numerator and denominator by 10 as long as you get in numerator the whole number.
0.233 = 0.233/1 = 2.33/10 = 23.3/100 = 233/1000
So, your answer is 233/1000 in fraction, I don't know if it's right, but just trying to help :)
