The correct statement that best describes Carlos’s idea is:
Carlos is correct. If the numerators are the same, the fraction with the lesser denominator will be greater.
When the numerators of two fractions are the same, the fraction with the smaller denominator represents a larger value. For example, \( \frac{5}{3} \) is greater than \( \frac{5}{4} \) because 3 is less than 4.
