Answer 3

To solve the expression, follow the order of operations (PEMDAS/BODMAS):

1. Parentheses/Brackets
2. Exponents/Orders
3. Multiplication and Division (from left to right)
4. Addition and Subtraction (from left to right)

Let's break down the expression step by step:

1. Start with the parentheses: (3 - 2 8/10 * 3/7)

   First, perform the multiplication: 2 8/10 * 3/7 = 2.8 * 3/7 = 0.4 * 3 = 1.2

   Now, subtract: 3 - 1.2 = 1.8

2. Now, we have the following expression: 8 25/100:1 1/10 - 1.8:6/10

3. Convert mixed numbers to improper fractions: 8 25/100 = (8 * 100 + 25) / 100 = 825/100 1 1/10 = (1 * 10 + 1) / 10 = 11/10

4. Perform the division: 825/100 ÷ 11/10

   To divide fractions, invert the second fraction and multiply: 825/100 * 10/11

   Now, simplify the fraction: 825/100 * 10/11 = (825 * 10) / (100 * 11) = 8250/1100

5. Simplify the fraction: 8250/1100 = (8250 ÷ 1100) / (1100 ÷ 1100) = 7.5 / 1 = 7.5

6. Now, we have the following expression: 7.5 - 1.8

7. Finally, perform the subtraction: 7.5 - 1.8 = 5.7

So, the simplified value of the expression is 5.7.
