Answer 2

To fully simplify the expression and perform the calculations, let's break it down step by step:

Step 1: Convert mixed numbers to improper fractions. 5 7/15 = (5 * 15 + 7) / 15 = 82/15 4 1/12 = (4 * 12 + 1) / 12 = 49/12 7 5/6 = (7 * 6 + 5) / 6 = 47/6 3 23/30 = (3 * 30 + 23) / 30 = 113/30 3,57 (assuming this is a decimal) remains as it is.

Step 2: Apply the necessary operations. 82/15 - 49/12 - (-1/12) - 113/30 + 47/6 - 3.57

Step 3: Convert the decimal to a fraction. 3.57 = 357/100

Step 4: Find a common denominator for all fractions. The common denominator for 15, 12, 30, and 6 is 60.

Step 5: Convert all fractions to have a denominator of 60. 82/15 = (82/15) * (4/4) = 328/60 49/12 = (49/12) * (5/5) = 245/60 (-1/12) = (-1/12) * (5/5) = -5/60 113/30 = (113/30) * (2/2) = 226/60 47/6 = (47/6) * (10/10) = 470/60 357/100 remains as it is.

Step 6: Perform the calculations. 328/60 - 245/60 + 5/60 - 226/60 + 470/60 - 357/100

Step 7: Combine like terms. (328 - 245 + 5 - 226 + 470 - 357) / 60

Step 8: Simplify the numerator. (475 - 583) / 60 = (-108) / 60 = -9/5

Therefore, the fully simplified expression is -9/5.
