1. The problem is to classify the given numbers and fractions as integers or non-integers. 2. The numbers given are: 20, 5, \frac{1}{5}, 15%, -10, and 15. 3. Recall that an integer is a whole number that can be positive, negative, or zero, without any fractional or decimal part. 4. Let's analyze each number: - 20 is an integer because it is a whole number. - 5 is an integer because it is a whole number. - \frac{1}{5} is a fraction and equals 0.2, which is not a whole number, so it is a non-integer. - 15% means 15 per 100, or 0.15, which is not a whole number, so it is a non-integer. - -10 is an integer because it is a whole number (negative integer). - 15 is an integer because it is a whole number. 5. Final classification: - Integers: 20, 5, -10, 15 - Non-integers: \frac{1}{5}, 15% This completes the classification of the given numbers.
