Answer 2

To solve the given expression, let's break it down step by step:

Step 1: Simplify the expression within parentheses

The expression inside the parentheses is: 15:3 + 3/4 - (10 + 1/2:1 + 1/2) * 3/14

First, let's simplify the division operation within the parentheses: 15:3 = 15/3 = 5

Now, the expression becomes: 5 + 3/4 - (10 + 1/2:1 + 1/2) * 3/14

Step 2: Simplify the expression within the second set of parentheses

The expression inside the second set of parentheses is: 10 + 1/2:1 + 1/2

Let's simplify the division operation within the second set of parentheses: 1/2:1 = (1/2) / 1 = 1/2

Now, the expression becomes: 5 + 3/4 - (10 + 1/2 + 1/2) * 3/14

Step 3: Simplify the expression within the second set of parentheses

The expression inside the second set of parentheses is: 10 + 1/2 + 1/2

Let's simplify the addition operation within the second set of parentheses: 10 + 1/2 + 1/2 = 10 + 1 = 11

Now, the expression becomes: 5 + 3/4 - (11) * 3/14

Step 4: Simplify the multiplication operation

Let's simplify the multiplication operation: (11) * 3/14 = 33/14

Now, the expression becomes: 5 + 3/4 - 33/14

Step 5: Simplify the addition and subtraction operations

To simplify the addition and subtraction operations, we need to find a common denominator for the fractions.

The common denominator for 4 and 14 is 28.

Converting 5 to a fraction with a denominator of 28: 5 = 5/1 = 140/28

Converting 3/4 to a fraction with a denominator of 28: 3/4 = (3/4) * (7/7) = 21/28

Now, the expression becomes: 140/28 + 21/28 - 33/14

Combining the fractions: (140 + 21 - 66) / 28 = 95/28

Final Answer

The simplified value of the expression (15:3 + 3/4 - (10 + 1/2:1 + 1/2) * 3/14):1 + 23/52 - 1 + 1/4 is 95/28.
