The expression is ¼ {1800 ÷ (11 × 24 – 8 × 3)} + ⅛. First, evaluate the operations inside the parentheses: 11 × 24 = 264 8 × 3 = 24 Subtract the results: 264 – 24 = 240. Substitute this back into the expression: ¼ {1800 ÷ 240} + ⅛. Next, perform the division inside the curly braces: 1800 ÷ 240 = 180 ÷ Finally, add ⅛: 15/8 + ⅛ = (15 + 1) / 8 = 16 / 8 = 2. The value of the expression is 2.
