To calculate the expression (4,4-0,63:1,8)*0,8, we need to follow the order of operations, which is parentheses, multiplication/division (from left to right), and then addition/subtraction (from left to right). First, let's simplify the expression inside the parentheses: 4,4 - 0,63 = 3,77 Next, let's divide 3,77 by 1,8: 3,77 ÷ 1,8 = 2,094444444444444 Finally, let's multiply the result by 0,8: 2,094444444444444 * 0,8 = 1,675555555555555 Therefore, (4,4-0,63:1,8)*0,8 equals approximately 1,6756.
