Answer 2

It seems like you've provided a mathematical expression involving absolute value and subtraction. Let's break it down step by step:

1. The expression starts with the absolute value notation, which is denoted by vertical bars (| |). The first absolute value expression is |- 17 1/3|°.

To evaluate this, we need to convert the mixed number 17 1/3 to an improper fraction. 17 1/3 is equivalent to (3 * 17 + 1) / 3 = 52/3.

Now we can calculate the absolute value of 52/3, which is simply 52/3 since the fraction is positive.

2. The next part of the expression is |- 9/52|. This is another absolute value expression.

The absolute value of 9/52 is simply 9/52 since the fraction is positive.

3. After the absolute value expressions, we have a subtraction operation: -.

Let's substitute the absolute values back into the expression:

(52/3)° - (9/52) - 1.5

To perform the subtraction, we need to find a common denominator for the fractions involved.

The common denominator for 3 and 52 is 156. So we can rewrite the expression as:

(52/3 * 52/52)° - (9/52 * 3/3) - (1.5 * 156/156)

Calculating each part separately:

(52/3 * 52/52)° = (2704/156)° = 17.33°

(9/52 * 3/3) = 27/156

(1.5 * 156/156) = 234/156

Substituting the calculated values back into the expression:

17.33° - 27/156 - 234/156

To subtract fractions, we need to have a common denominator, which is already 156 in this case. So we can directly subtract the fractions:

(17.33° * 156/156) - (27/156) - (234/156) = (2696.28/156) - (27/156) - (234/156)

Now, combining the fractions:

(2696.28 - 27 - 234) / 156 = 2435.28 / 156

The result is approximately 15.6051282.

Therefore, the simplified value of the given expression is approximately 15.6051282.
