The process of adding these fractions is a fundamental skill in arithmetic and a crucial step in solving our problem. To add fractions, we need to find a common denominator. This is a number that all the denominators (4, 5, and 20) can divide into evenly. In this case, the least common multiple of 4, 5, and 20 is 20. So, we'll convert each fraction to an equivalent fraction with a denominator of 20. Let's start with 1/4. To convert it to a fraction with a denominator of 20, we multiply both the numerator and the denominator by 5: (1 * 5) / (4 * 5) = 5/20. Next, let's convert 2/5 to a fraction with a denominator of 20. We multiply both the numerator and the denominator by 4: (2 * 4) / (5 * 4) = 8/20. The fraction 7/20 already has the desired denominator, so we don't need to change it. Now that we have all the fractions with a common denominator, we can add them together: 5/20 + 8/20 + 7/20. To add fractions with the same denominator, we simply add the numerators and keep the denominator the same: (5 + 8 + 7) / 20 = 20/20. The result is 20/20, which simplifies to 1. This means that the teacher has corrected 1 whole, or all, of the test papers. This result confirms our understanding that the teacher's efforts across the three days have successfully completed the task. It also demonstrates the power of fractions in representing portions of a whole and how they can be combined to solve real-world problems.
