Answer 2

To solve the given expressions, we need to follow the order of operations (PEMDAS/BODMAS). This means we should first perform the multiplication, then the division, and finally the subtraction. Let's break down each expression step by step:

1. 81 × 12 ÷ 24 × 45 Step 1: 81 × 12 = 972 Step 2: 972 ÷ 24 = 40.5 Step 3: 40.5 × 45 = 1822.5

2. 56 × 17 ÷ 48 × 49 Step 1: 56 × 17 = 952 Step 2: 952 ÷ 48 = 19.8333333... (repeating decimal) Step 3: 19.8333333... × 49 = 970.8333333... (repeating decimal)

Now, we subtract the second result from the first:

1822.5 - 970.8333333...

Without a specific number of decimal places requested, we'll keep the result as a decimal:

≈ 851.6666667... (repeating decimal)

So, the final result of the given expression is approximately 851.67.
