Answer 2

To solve the expression (12 2/3 + 0.7 - 12.7) ÷ 0.05, let's break it down step by step:

Step 1: Convert mixed numbers to improper fractions 12 2/3 can be converted to an improper fraction as follows: 12 2/3 = (3 * 12 + 2)/3 = 38/3

Step 2: Perform addition and subtraction (38/3 + 0.7 - 12.7) ÷ 0.05

38/3 + 0.7 = (38/3) + (7/10) = (38/3) + (21/30) = (38/3) + (7/30) = (380/30) + (7/30) = 387/30

Now the expression becomes: (387/30 - 12.7) ÷ 0.05

387/30 - 12.7 = (387/30) - (127/10) = (387/30) - (381/30) = 6/30 = 1/5

Now the expression becomes: (1/5) ÷ 0.05

Step 3: Divide by 0.05 To divide by 0.05, we can multiply by its reciprocal (1/0.05): (1/5) ÷ 0.05 = (1/5) * (1/0.05) = (1/5) * (20/1) = 20/5 = 4

Therefore, the value of the expression (12 2/3 + 0.7 - 12.7) ÷ 0.05 is 4.
