Answer 2

Let's solve the expression step by step:

Step 1: Perform operations inside parentheses. (12, 75 - 1 19/20) + (1 1/9 * (-12, 6) / 2 2/5) + (9 4/16)

Step 2: Convert mixed numbers to improper fractions. (12 75/1 - 1 19/20) + (1 1/9 * -12 6/1) / (2 2/5) + (9 4/16)

Step 3: Perform subtraction and multiplication. (12 56/20) + (-13 1/9) / (2 2/5) + (9 1/4)

Step 4: Convert mixed numbers back to mixed numbers and improper fractions to mixed numbers (if possible). (12 + 56/20) + (-13 + 1/9) / (2 + 2/5) + (9 + 1/4)

Step 5: Convert improper fractions to mixed numbers. (12 + 2 16/20) + (-13 + 1/9) / (2 + 2/5) + (9 + 1/4)

Step 6: Perform addition and subtraction. (12 + 1 4/5) + (-12 8/9) / (2 + 2/5) + (9 + 1/4)

Step 7: Convert mixed numbers to improper fractions. (12 + 9/5) + (-116/9) / (12/5) + (37/4)

Step 8: Perform addition. (60/5 + 9/5) + (-116/9) / (12/5) + (37/4)

Step 9: Convert the result back to mixed number (if possible). (69/5) + (-116/9) / (12/5) + (37/4)

Step 10: Perform division. (69/5) + (-116/9) * (5/12) + (37/4)

Step 11: Perform multiplication. (69/5) + (-116 * 5) / (9 * 12) + (37/4)

Step 12: Perform multiplication and addition. (69/5) - (580/108) + (37/4)

Step 13: Convert the result back to mixed number (if possible). (69/5) - (145/27) + (37/4)

Step 14: Find a common denominator for the fractions (4, 5, and 27). The common denominator is 540.

Step 15: Rewrite the fractions with the common denominator. (138/10) - (725/540) + (740/540)

Step 16: Perform subtraction and addition. (138/10) - (725/540 + 740/540)

Step 17: Combine the fractions. (138/10) - (1465/540)

Step 18: Convert the result to a mixed number. (138/10) - (2 425/540)

Step 19: Reduce the mixed number (if possible). (138/10) - (2 85/540)

Step 20: Convert the mixed number back to an improper fraction. (138/10) - (115/54)

Step 21: Find a common denominator for the fractions (10 and 54). The common denominator is 540.

Step 22: Rewrite the fractions with the common denominator. (138/10 * 54/54) - (115/54)

Step 23: Perform multiplication. (138 * 54) / (10 * 54) - (115/54)

Step 24: Perform division. (7452/540) - (115/54)

Step 25: Find a common denominator for the fractions (540 and 54). The common denominator is 540.

Step 26: Rewrite the fractions with the common denominator. (7452/540) - (10 * 115/540)

Step 27: Perform multiplication. (7452/540) - (1150/540)

Step 28: Perform subtraction. (7452/540) - (1150/540) = 6302/540

Step 29: Simplify the fraction (if possible). 6302/540 = 3151/270

Step 30: Convert the fraction to a mixed number. 3151/270 ≈ 11 101/270

So, the final result is approximately 11 101/270.
