Answer 2

A) Calculation: 4 1/3 * 1 5/6 - 4 1/3 * 3 5/6

To calculate this expression, we can follow the order of operations (PEMDAS/BODMAS) and simplify step by step.

Step 1: Convert the mixed numbers to improper fractions. - 4 1/3 = (4 * 3 + 1) / 3 = 13/3 - 1 5/6 = (1 * 6 + 5) / 6 = 11/6 - 3 5/6 = (3 * 6 + 5) / 6 = 23/6

Step 2: Perform the multiplication. - 13/3 * 11/6 = (13 * 11) / (3 * 6) = 143/18

Step 3: Perform the second multiplication. - 13/3 * 23/6 = (13 * 23) / (3 * 6) = 299/18

Step 4: Perform the subtraction. - 143/18 - 299/18 = (143 - 299) / 18 = -156/18 = -13/3

Therefore, the value of the expression 4 1/3 * 1 5/6 - 4 1/3 * 3 5/6 is -13/3.

B) Calculation: 4 1/5 * 5 7/9 + (-4 1/5) * 3 5/9 - 41/5 * 1 2/9

Let's calculate this expression step by step.

Step 1: Convert the mixed numbers to improper fractions. - 4 1/5 = (4 * 5 + 1) / 5 = 21/5 - 5 7/9 = (5 * 9 + 7) / 9 = 52/9 - -4 1/5 = (-4 * 5 + 1) / 5 = -19/5 - 3 5/9 = (3 * 9 + 5) / 9 = 32/9 - 41/5 = 41/5 - 1 2/9 = (1 * 9 + 2) / 9 = 11/9

Step 2: Perform the multiplications. - 21/5 * 52/9 = (21 * 52) / (5 * 9) = 1092/45 - -19/5 * 32/9 = (-19 * 32) / (5 * 9) = -608/45 - 41/5 * 11/9 = (41 * 11) / (5 * 9) = 451/45

Step 3: Perform the additions and subtractions. - 1092/45 + (-608/45) - 451/45 = (1092 - 608 - 451) / 45 = 33/45 = 11/15

Therefore, the value of the expression 4 1/5 * 5 7/9 + (-4 1/5) * 3 5/9 - 41/5 * 1 2/9 is 11/15.

I hope this helps! Let me know if you have any further questions.
