Here are the calculations for the circled problems: 1.1 To divide by 10, move the decimal point one place to the left. 2,64 ÷ 10 = 0,264 The answer is 0,264. 1.3 To divide by 1000, move the decimal point three places to the left. 973,4 ÷ 1000 = 0,9734 The answer is 0,9734. 1.4 To divide by 100, move the decimal point two places to the left. 5,76 ÷ 100 = 0,0576 The answer is 0,0576. 2.3 Step 1: Set up the long division. r 9.82 \\ 9 ) 88.38 \\ Step 2: Divide 88 by 9. 9 × 9 = 81. r 9. \\ 9 ) 88.38 \\ -81 \\ 7 \\ Step 3: Bring down the next digit (3) after the decimal point. Place the decimal point in the quotient. Divide 73 by 9. 9 × 8 = 72. r 9.8 \\ 9 ) 88.38 \\ -81 \\ 73 \\ -72 \\ 1 \\ Step 4: Bring down the next digit (8). Divide 18 by 9. 9 × 2 = 18. r 9.82 \\ 9 ) 88.38 \\ -81 \\ 73 \\ -72 \\ 18 \\ -18 \\ 0 \\ The answer is 9,82. 2.4 Step 1: Set up the long division. r 3.61 \\ 12 ) 43.32 \\ Step 2: Divide 43 by 12. 12 × 3 = 36. r 3. \\ 12 ) 43.32 \\ -36 \\ 7 \\ Step 3: Bring down the next digit (3) after the decimal point. Place the decimal point in the quotient. Divide 73 by 12. 12 × 6 = 72. r 3.6 \\ 12 ) 43.32 \\ -36 \\ 73 \\ -72 \\ 1 \\ Step 4: Bring down the next digit (2). Divide 12 by 12. 12 × 1 = 12. r 3.61 \\ 12 ) 43.32 \\ -36 \\ 73 \\ -72 \\ 12 \\ -12 \\ 0 \\ The answer is 3,61.
