- 4/7 - 3/4
write your answer in simplest form.

or negative

Step-by-step explanation:

Find the least common multiple of the two denominators.

The LCM is 28.

To get to 28 using 7, you multiply it by 4, so we do it to its numerator as well.

4*4 = 16.

The first fraction is now - 16/28.

Just do the same to the next fraction.

4 times 7 (we used 7 instead of 4 to get to 28) equals 28.

3*7 = 21.

The second fraction is 21/28.

Now that the two denominators are the same, let's subtract the two fractions.

(note that -16/28 is the same as - 16/28)

- =

(-16) - 21 = -37

So, the answer is , but can it be simplified any more? I don't think so.

There's your answer! or negative
