ok well i am really working on this :
5 1/6 - 4 4/7 (6x7=42) (1x7=7 = 7/42 ) (4x6=24 = 24/42)
7 - 24 = 17
= 17/42 ........... wat do i do next ? can i simplify it ? am i right ?

I changed the whole numbers into fractions as well then found the common denomenator as follows:
5x6+1=31 so 5 1/6 = 31/6
4x7+4=32 so 4 4/7 = 32/7
so common denomenator is 42
31/6 x 7/7 = 217/42
32/7 x 6/6 = 192/42
217-192 = 25
so your answer would be 25/42 and it cannot be reduced.

5 1/6 - 4 4/7 = 1 1/6 - 4/7
1 1/6 = 7/6 = 49/42
4/7 = 24/42
49/42 - 24/42 = 25/42
25 = 5*5, 42 = 6*7
no common factors, so it cannot be reduced

5 1/6 -4 4/7=
31/6 - 32/7=
217/42-192/42=25/42
25/42 can not be reduced any further.

if your question is 5 1/6 - 4 4/7., your answer is wrong.
5 1/6 - 4 4/7= 31/6 - 32/7
= (217-192)/42
= 25/42

No. because 17 is a prime number and 24 is not a multipleof 17

You cannot reduce 17/24.

"can you reduce 17/24 ?"
.: Answer: It's impossible to reduce that fraction because GCF between 17 and 24 is 1. There is no common denominator.

17/24 is as reduced as it will be.

17 is a prime #, so 17 over anything that is not an integer multiple of 17 can't be reduced.
