Answer 2

To solve this expression, you can add and subtract the fractions in order.

1/2 - 2/3 + 4/5 - 5/6 + 14/15

First, find a common denominator for all the fractions. In this case, the least common denominator is 30.

Now, convert each fraction to have a denominator of 30:

(1/2) * (15/15) = 15/30 (2/3) * (10/10) = 20/30 (4/5) * (6/6) = 24/30 (5/6) * (5/5) = 25/30 (14/15) * (2/2) = 28/30

Now, your expression becomes:

15/30 - 20/30 + 24/30 - 25/30 + 28/30

Now, you can simply add and subtract the fractions:

(15 - 20 + 24 - 25 + 28) / 30

(-18) / 30

Now, you can simplify the fraction by dividing both the numerator and the denominator by their greatest common divisor, which is 6:

(-18 ÷ 6) / (30 ÷ 6)

-3/5

So, the result of the expression 1/2 - 2/3 + 4/5 - 5/6 + 14/15 is -3/5.
