Answer 2

Calculation of the Expression

To find the value of the given expression, we'll perform the following steps:

1) Calculate the value of the expression within the parentheses. 2) Perform the multiplication and subtraction operations in the order they appear.

Let's start by calculating the value of the expression within the parentheses.

Calculation Within the Parentheses

1) For the first expression within the parentheses: - 5 3/4 * 8 - 2 1/3 * 1 3/14 - 1 37/48 * 2 2/15

2) For the second expression within the parentheses: - 2 7/10 - 1 8/15

Calculation of the First Expression Within the Parentheses

The first expression within the parentheses involves multiplication and subtraction. Let's calculate it step by step.

1) 5 3/4 * 8 - The product of 5 3/4 and 8 is 46.

2) 2 1/3 * 1 3/14 - The product of 2 1/3 and 1 3/14 is 7/14.

3) 1 37/48 * 2 2/15 - The product of 1 37/48 and 2 2/15 is 5/15.

Now, we'll perform the subtraction operation: - 46 - 7/14 - 5/15

Calculation of the Second Expression Within the Parentheses

The second expression within the parentheses involves subtraction. Let's calculate it.

1) 2 7/10 - 1 8/15 - The difference between 2 7/10 and 1 8/15 is 1 19/30.

Final Calculation

Now, we'll perform the final calculation using the results from the expressions within the parentheses.

1) (46 - 7/14 - 5/15) * (1 19/30) * 9/14

Let's calculate the final value of the expression.
