Answer 3

To solve the expression (1.6 × 2.15 - 0.23) ÷ (3.45 - 3 3/4), we need to follow the order of operations, which is typically abbreviated as PEMDAS/BODMAS (Parentheses/Brackets, Exponents/Orders, Multiplication/Division, Addition/Subtraction).

Step 1: Perform the operations inside the parentheses/brackets first. 1.6 × 2.15 = 3.44 (rounded to two decimal places) 3 3/4 = 3.75

Step 2: Perform the subtraction inside the parentheses. 3.45 - 3.75 = -0.30 (rounded to two decimal places)

Step 3: Perform the multiplication. 3.44 - 0.23 = 3.21 (rounded to two decimal places)

Step 4: Perform the division. 3.21 ÷ -0.30 = -10.7 (rounded to one decimal place)

Therefore, the result of the expression is approximately -10.7.
