-1/2 - (-3/4)

Answer 1

To solve this expression, we need to simplify it step by step.

To start, we can remove the parentheses by multiplying (-1/2) by -1, which gives us:

-1 * (-1/2) = 1/2

Now, let's simplify the second part of the expression:

-3/4

Finally, we can subtract the two simplified parts:

1/2 - 3/4

To subtract fractions, we need a common denominator. The common denominator here is 4. So, we need to make both fractions have a denominator of 4:

1/2 * 2/2 = 2/4

Now, we can subtract the fractions:

2/4 - 3/4 = -1/4

Therefore, -1/2 - (-3/4) simplifies to -1/4.
