Answer 2

To subtract mixed numbers, we need to find a common denominator for the fractions involved. Let's calculate the expression -1 7/9 - 3 5/6 - 21/16 - 5 1/3 step by step.

Step 1: Convert the mixed numbers to improper fractions: -1 7/9 = -(9/9 + 7/9) = -16/9 3 5/6 = 3(6/6) + 5/6 = 18/6 + 5/6 = 23/6 5 1/3 = 5(3/3) + 1/3 = 15/3 + 1/3 = 16/3

Step 2: Find a common denominator for all the fractions involved, which is 9 * 6 * 16 = 864.

-16/9 = -16/9 * 96/96 = -1536/864 23/6 = 23/6 * 144/144 = 3312/864 21/16 = 21/16 * 54/54 = 1134/864 16/3 = 16/3 * 288/288 = 4608/864

Step 3: Subtract the fractions:

-1536/864 - 3312/864 - 1134/864 - 4608/864 = (-1536 - 3312 - 1134 - 4608)/864 = -10590/864

Step 4: Simplify the fraction, if possible:

-10590/864 = -1225/99

Therefore, the expression -1 7/9 - 3 5/6 - 21/16 - 5 1/3 is equal to -1225/99.
