Answer 2

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

Step 1: Simplify the expressions inside the parentheses.

• 1: 1/25 - 2.5: 1/10 To perform the operations, we need to convert the mixed numbers to improper fractions. 1: 1/25 = (1 * 25 + 1) / 25 = 26/25 2.5: 1/10 = (2 * 10 + 1) / 10 = 21/10

Now, we can subtract these fractions: 26/25 - 21/10

To subtract fractions, we need to find a common denominator, which is 50 in this case. 26/25 * 2/2 = 52/50 21/10 * 5/5 = 105/50

Now we can subtract: 52/50 - 105/50 = -53/50

Step 2: Simplify the expression inside the second parentheses.

• 0.5 + 13 1/3 13 1/3 = 13 + 1/3 = 40/3 0.5 = 1/2

Now we can add:

• 1/2 + 40/3

To add fractions, we need a common denominator, which is 6 in this case.

• 1/2 * 3/3 = -3/6 40/3 * 2/2 = 80/6

Now we can add:

• 3/6 + 80/6 = 77/6

Step 3: Perform the multiplication and division.

• 2 - (53/50 * 8 8/17) 8 8/17 = 8 + 8/17 = 136/17

Now, let's perform the multiplication: 53/50 * 136/17 = (53 * 136) / (50 * 17) = 7188 / 850

Step 4: Continue with the subtraction.

• 2 - (7188/850) To perform this subtraction, we need to convert 2 to a fraction with the same denominator as 850. 2 = 2/1

Now, we can perform the subtraction: 2/1 - 7188/850

To subtract fractions, we need a common denominator, which is 850 in this case. 2/1 * 850/850 = 1700/850 7188/850

Now we can subtract: 1700/850 - 7188/850 = -5488/850

Step 5: Perform the final addition.

• 5488/850 + 5/14 - 2 1/3 (77/6) 2 1/3 = 2 + 1/3 = 7/3

Now, let's add the fractions:

• 5488/850 + 5/14 - 7/3

To add fractions, we need a common denominator, which is 850 in this case. 5/14 * 50/50 = 250/850 7/3 * 283/283 = 849/850

Now we can add:

• 5488/850 + 250/850 - 849/850 = -6087/850

The final result is: -6087/850
