Answer 2

Let's simplify each of these expressions step by step:

1. -3/8 - 3/4 + 3/2

First, find a common denominator, which is 8:

-3/8 - 6/8 + 12/8

Now that the denominators are the same, you can combine the fractions:

(-3 - 6 + 12)/8 = 3/8

So, the result is 3/8.

2. -1/6 - 1/6 - 1/6

These fractions already have a common denominator, which is 6:

-1/6 - 1/6 - 1/6 = (-1 - 1 - 1)/6 = -3/6

Now, simplify the fraction by dividing both the numerator and denominator by their greatest common divisor, which is 3:

-3/6 = (-1/2)

So, the result is -1/2.

3. 1/9 - 1/3 + 1/18

First, find a common denominator, which is 18:

2/18 - 6/18 + 1/18

Now that the denominators are the same, you can combine the fractions:

(2 - 6 + 1)/18 = -3/18

Simplify the fraction by dividing both the numerator and denominator by their greatest common divisor, which is 3:

-3/18 = (-1/6)

So, the result is -1/6.

4. 2/3 - 1/5 - 1/15

First, find a common denominator, which is 15:

10/15 - 3/15 - 1/15

Now that the denominators are the same, you can combine the fractions:

(10 - 3 - 1)/15 = 6/15

Simplify the fraction by dividing both the numerator and denominator by their greatest common divisor, which is 3:

6/15 = (2/5)

So, the result is 2/5.
