What is -5/12 - 4/14 + 6/34

Mathematics
1 answer:
andrew11 [14]3 years ago
5 0

Answer:

4 1/2

Step-by-step explanation:

Look at this expression as given in the original problem; the numbers, properly typewritten, are    -5  1/2,  - 4  1/4,  + 6  3/4.

We want to combine these three numbers into one.

To do this, we need the LCD; it is 4.

Thus, -5  1/2 is rewritten as  -5  2/4.

Then we have

-5  2/4 - 4  1/4 + 6  3/4  = -5 -4 + 6 + 2/4 + 1/4 + 3/4.

This simplifies to:                 +3 + 6/4, or 3 + 1  + 2/4, or

                                                                      4  1/2
