Answer 2

Let's solve each expression step by step:

1. (7 × 63) ÷ 7 First, perform the multiplication inside the parentheses: 7 × 63 = 441 Then, divide the result by 7: 441 ÷ 7 = 63

2. (3 × 4 × 5) ÷ 15 First, perform the multiplication inside the parentheses: 3 × 4 × 5 = 60 Then, divide the result by 15: 60 ÷ 15 = 4

3. (15 × 18) ÷ (5 × 6) First, perform the multiplication inside the first set of parentheses: 15 × 18 = 270 Next, perform the multiplication inside the second set of parentheses: 5 × 6 = 30 Then, divide the first result by the second result: 270 ÷ 30 = 9

Putting it all together, the final result is:

63 - 4 - 9 = 50
