Question

5 1/8 - 2 3/4 plz help

Answer 1

First you would have to make them improper fractions,

that would make it 41/8 and 12/4
then you would make them have like denominators. 41/8 = 41/8 and 12/4 = 24/8. then you would subtract them. 

The you will get 17/8. if you want a mix number than just divide 17 by 8!

Answer 2

You can first turn both numbers into a improper fraction so it looks like this: 41/8-11/4. 
Then you have to change the denominator so that they are the same, which looks like this: 41/8-22/8.
After, you subtract the numerator and keep the denominator the same, which will then look like this 19/8.
Lastly, you turn your numbers back into a mixed number so it is 2 3/8.
