*improper*

Answer 6

yes. then you find the GCF

Answer 7

the denominators have to be the same

Answer 8

ok one sec

Answer 9

omg brain fart. how do you you find the greatest common factor of 17/3 and 18/7?

Answer 10

If you multiply 3 by 7 you get 18 so that would be the greatest common factor

then to apply that to the problem you multiply 17/3 by 7/7
18/7 by 3/3

Answer 11

oh ok..

Answer 12

ok i got 119/21 and 54/21

multiply 52/7 by 3/3

Answer 20

then add them together

Answer 21

ok

Answer 22

156/21?

Answer 23

now i add 156/21 + 225/28?

Answer 24

yes. now you need to subtract 12 from both sides

to do that with fractions you make 12 look like this: 12/1

then find the GCF which is 21 then multiply 21/1 by 21/21

Answer 25

ok

Answer 26

then subtract and you will have n

Answer 27

and remeber to put it in improper form

Answer 28

144/21 and 213/28

Answer 29

now find the greaest common factor.
