What a load of weirdness. Of course, Randy, Jerome, Ali, and the MeGirl are correct.

Sami's answer, with a denominator of 8, is impossible, starting with a denominator of 3.

the bcnChick interpreted the question as 52/3 - 27/8.

Madely's method of dealing with fractions is the strangest I have ever seen, and wrong to boot.

5 2/3=17/3
2 7/8=23/8
17/3-23/8=(17*8-23*3)/24
(136-69)/24
67/24
2 19/24

I'll answer because you got different answers from several persons.
5 2/3 – 2 7/8 = 17/3 – 23/8
.................. = 136/24 – 69/24
.................. = 67/24
.................. = 2 19/24

5 2/3 - 2 7/8 = 17/3 - 23/8 = 136/24 - 69/24 = 67/24 = 2 19/24

2 19/24

You need to find the common denominator

5 x 3 + 2 =17/5
2 x 8 + 7 = 24/8

5/ 8 = 1.6 so times that part of the equation by this number
27.2/ 8 - 24/8 =
3.2/ 8

I'm sorry if this is the wrong answer, but it should be near correct lol

5 2/3 - 2 7/8 is 17/3 - 23/8 then 136/24 - 69/24 = 67/24 or 2 19/24.

3 + 16/24 - 21/24

2 + 40/24 - 21/24

2 + 19/24

2 19/24

5 2/3 - 2 7/8
= 5 (2 x 8)/(3 x 8) - 2 (7 x 3)/(8 x 3)
= 5 16/24 - 2 21/24
= (5 - 2) + (16/24 - 21/24)
= 3 + (-5/24)
= 2 24/24 - 5/24
= 2 19/24
