Answer 2

To solve the given expression, we need to perform the arithmetic operations step by step:

Step 1: Add the fractions within each mixed number. Step 2: Add the whole numbers separately.

Let's do the calculations:

Step 1: 3 (5/6) = 3 + 5/6 2 (7/15) = 2 + 7/15 1 (29/30) = 1 + 29/30

Step 2: 3 + 5/6 = (3 * 6 + 5) / 6 = (18 + 5) / 6 = 23/6 2 + 7/15 = (2 * 15 + 7) / 15 = (30 + 7) / 15 = 37/15 1 + 29/30 = (1 * 30 + 29) / 30 = (30 + 29) / 30 = 59/30

Now, the expression becomes: (23/6) + (37/15) - (59/30)

To add the fractions, we need a common denominator. The least common multiple (LCM) of 6, 15, and 30 is 30.

Converting each fraction to have a denominator of 30: (23/6) = (23/6) * (5/5) = (115/30) (37/15) = (37/15) * (2/2) = (74/30) (59/30) remains unchanged.

Now, the expression becomes: (115/30) + (74/30) - (59/30)

Now, we can combine the fractions: (115 + 74 - 59) / 30 = 130 / 30

Finally, we can simplify the fraction: 130 / 30 = 13/3

So, the result of the expression is 13/3.
