Calculating Arithmetic Expressions

Let's break down the given arithmetic expressions step by step.

1. 19/28 - 16/28 - 17/28: - To solve this, we can combine the fractions with the same denominator. - The result is: 19/28 - 16/28 - 17/28 = (19 - 16 - 17)/28 = -14/28 = -1/2.

2. 4 11/14 - 2 5/14 + 1 3/14: - First, convert the mixed numbers to improper fractions. - Then, combine the fractions with the same denominator. - The result is: 4 11/14 - 2 5/14 + 1 3/14 = (4 + 11/14) - (2 + 5/14) + (1 + 3/14) = (4 + 11/14) - (2 + 5/14) + (1 + 3/14) = (4 - 2 - 1) + (11/14 - 5/14 + 3/14) = 1 + 9/14 = 1 9/14.

3. 1 - 8/17: - Subtract the fraction from the whole number. - The result is: 1 - 8/17 = 1 - 8/17 = (17/17) - 8/17 = 9/17.

4. 4 5/9 - 2 8/9: - Similar to the previous expression, convert the mixed numbers to improper fractions and then perform the subtraction. - The result is: 4 5/9 - 2 8/9 = (4 + 5/9) - (2 + 8/9) = (4 - 2) + (5/9 - 8/9) = 2 - 3/9 = 1 2/9.

So, the results of the given arithmetic expressions are: - 19/28 - 16/28 - 17/28 = -1/2 - 4 11/14 - 2 5/14 + 1 3/14 = 1 9/14 - 1 - 8/17 = 9/17 - 4 5/9 - 2 8/9 = 1 2/9
