Answer 2

3 1/2 - 7 + 2/3

To solve this expression, we can start by converting the mixed number, 3 1/2, to an improper fraction.

3 1/2 = (3 * 2 + 1) / 2 = 7/2

Now we can substitute this value back into the original expression:

7/2 - 7 + 2/3

We need to find a common denominator for 2 and 3, which is 6. Let's convert the fractions:

(7/2) * (3/3) = 21/6 (2/3) * (2/2) = 4/6

Now we can rewrite the expression:

21/6 - 7 + 4/6

The next step is to subtract the fractions:

21/6 - 7 + 4/6 = 21/6 - 42/6 + 4/6

Since the denominators are the same, we can simply add or subtract the numerators:

= (21 - 42 + 4) / 6 = (-17) / 6

So the final answer is -17/6.
