9.524 written as a mixed number would be 9 131/250 because 9 is the whole number, and then you make 524 into a fraction. This would be 524/1000. When you simplify this fraction you get 131/250. Smash these two numbers together and you get 9 131/250. I know that this is a big fraction, but 131 is a prime number, and cannot be divided without using a decimal.
