Answer 2

To solve the expression, we need to follow the order of operations, which is commonly known as PEMDAS (Parentheses, Exponents, Multiplication and Division from left to right, and Addition and Subtraction from left to right).

Let's calculate the expression step by step:

1. Multiply: 20 × 15 = 300
2. Multiply: 35 × 15 = 525
3. Divide: 31 ÷ 140 = 0.2214 (rounded to four decimal places)
4. Divide: 0.2214 ÷ 51 = 0.00434 (rounded to five decimal places)
5. Add: 300 + 525 = 825
6. Subtract: 825 - 0.00434 = 824.99566 (rounded to five decimal places)

Therefore, the result of the expression 20 × 15 + 35 × 15 - 31 ÷ 140 ÷ 51 is approximately 824.99566.
