Final answer:
To convert 33.3 to a fraction, it becomes 333/10, which is already in its simplest form since the numerator and denominator do not have any common factors other than 1.
Step-by-step explanation:
To express the number 33.3 as a fraction, we should recognize that 33.3 is equivalent to 33.3/1. Since there is a single decimal place, we multiply the numerator and denominator by 10 to eliminate the decimal, resulting in 333/10. However, we can simplify this fraction further. Both the numerator and denominator have a common factor of 1 (as any number divided by itself is 1), so the fraction remains as 333/10, which is the simplest form.
