Answer 2

To solve the expression, let's break it down step by step:

Step 1: Perform operations inside the parentheses. 12 75/100 - 6 11/12 + 14 8/10 - 7 2/5

Step 2: Convert all the mixed fractions to improper fractions (fractions with the numerator greater than the denominator). 12 75/100 = (12 * 100 + 75) / 100 = 1275 / 100 6 11/12 = (6 * 12 + 11) / 12 = 83 / 12 14 8/10 = (14 * 10 + 8) / 10 = 148 / 10 7 2/5 = (7 * 5 + 2) / 5 = 37 / 5

So the expression becomes: (1275/100 - 83/12 + 148/10 - 37/5) / (10 2/3 - 3 11/12)

Step 3: Perform the operations inside the parentheses. (1275/100 - 83/12 + 148/10 - 37/5)

Step 4: Find a common denominator for all the fractions in the numerator, which is 60. (1275/100) = (1275/100) * (60/60) = 76500 / 6000 (83/12) = (83/12) * (5/5) = 415 / 60 (148/10) = (148/10) * (6/6) = 888 / 60 (37/5) = (37/5) * (12/12) = 444 / 60

So the expression becomes: (76500/6000 - 415/60 + 888/60 - 444/60)

Step 5: Combine the fractions in the numerator. (76500/6000 - 415/60 + 888/60 - 444/60) = (76500 - 415 + 888 - 444) / 60 = 76129 / 60

Step 6: Convert the whole number in the denominator to an improper fraction. 10 2/3 = (10 * 3 + 2) / 3 = 32 / 3

Step 7: Perform the operation with the denominator. 76129 / 60 ÷ 32 / 3

Step 8: Invert the second fraction and change the division to multiplication. 76129 / 60 × 3 / 32

Step 9: Cancel out common factors between the numerator and denominator, if any. In this case, there are no common factors, so we leave the fractions as they are.

Step 10: Multiply the fractions. (76129 × 3) / (60 × 32) = 228387 / 1920

So, the simplified result of the expression is: 228387 / 1920
