Answer 2

To solve the expression 20.8:(12-11.36)-8:12.5, you can follow the order of operations, which is typically represented by the acronym PEMDAS:

1. P: Parentheses first
2. E: Exponents (none in this expression)
3. MD: Multiplication and Division (from left to right)
4. AS: Addition and Subtraction (from left to right)

Let's break down the expression step by step:

1. Start with the parentheses: 12 - 11.36 = 0.64

So, the expression becomes: 20.8 / 0.64 - 8 / 12.5

2. Now, perform the division from left to right: 20.8 / 0.64 ≈ 32.5 8 / 12.5 ≈ 0.64

So, the expression becomes: 32.5 - 0.64

3. Finally, subtract: 32.5 - 0.64 ≈ 31.86

The result of the expression is approximately 31.86.
