Answer 2

Let's solve each of the expressions step by step:

1. 100 - 54 ÷ 23 × 19 + 22

Step 1: Division 54 ÷ 23 = 2.347826 (rounded to 6 decimal places)

Step 2: Multiplication 2.347826 × 19 = 44.736842 (rounded to 6 decimal places)

Step 3: Subtraction 100 - 44.736842 = 55.263158 (rounded to 6 decimal places)

Step 4: Addition 55.263158 + 22 = 77.263158 (rounded to 6 decimal places)

So, the result of the expression is approximately 77.263158.

2. 100 - 13 ÷ 3 + 27 ÷ 14

Step 1: Division 13 ÷ 3 = 4.333333 (repeating) (rounded to 6 decimal places)

Step 2: Division 27 ÷ 14 = 1.928571 (rounded to 6 decimal places)

Step 3: Subtraction 100 - 4.333333 = 95.666667 (repeating) (rounded to 6 decimal places)

Step 4: Addition 95.666667 + 1.928571 = 97.595238 (rounded to 6 decimal places)

So, the result of the expression is approximately 97.595238.

3. 98 - 59 ÷ 3 + 27 ÷ 14

Step 1: Division 59 ÷ 3 = 19.666667 (repeating) (rounded to 6 decimal places)

Step 2: Division 27 ÷ 14 = 1.928571 (rounded to 6 decimal places)

Step 3: Subtraction 98 - 19.666667 = 78.333333 (repeating) (rounded to 6 decimal places)

Step 4: Addition 78.333333 + 1.928571 = 80.261904 (rounded to 6 decimal places)

So, the result of the expression is approximately 80.261904.
