What is 3/4 - 1/2?...Please explain...Rewarding Brainliest...
PSYCHO15rus [73]

Answer:

1/4

Step-by-step explanation:

Find common denominators. Note that what you multiply (or divide) from the denominator, you must also do the same to the numerator.

In this case, the common denominator would be 4. Multiply 2 to both the numerator & denominator of (-1/2):

(-1/2) * (2/2) = (-1 * 2)/(2 * 2) = -2/4

Subtract across:

3/4 - 2/4 = (3 - 2)/4 = 1/4

1/4 is your answer.
