Answer 2

To solve the expression 5 9/10 - (4 7/10 - 1 9/10), we need to perform the subtraction operations within the parentheses first. Let's break it down step by step:

1. Start with the innermost subtraction operation: 4 7/10 - 1 9/10. To subtract mixed numbers, we need to convert them to improper fractions. 4 7/10 = (4 * 10 + 7) / 10 = 47/10 1 9/10 = (1 * 10 + 9) / 10 = 19/10

   Now, subtract the fractions: 47/10 - 19/10 = (47 - 19) / 10 = 28/10

2. Now, we have 5 9/10 - (28/10). To subtract mixed numbers, we need to convert the whole number part to a fraction. 5 = 5 * 10/10 = 50/10

   Now, subtract the fractions: 50/10 - 28/10 = (50 - 28) / 10 = 22/10

3. The result is 22/10, which can be simplified. Divide the numerator and denominator by their greatest common divisor (GCD), which is 2. 22/10 = (22 ÷ 2) / (10 ÷ 2) = 11/5

Therefore, 5 9/10 - (4 7/10 - 1 9/10) equals 11/5 or 2 1/5.
