1/4+w=19/3
w=19/3-1/4
w=(19*4-1*3)/12
w=73/12=6 1/12
OpenStudy (fouzberzerk):
It has to equal 6 1/3
OpenStudy (er.mohd.amir):
no 6 and 1/12
OpenStudy (fouzberzerk):
6 and 1/3 look at the problem.
OpenStudy (fouzberzerk):
1/4 + w = 6 1/3

6 1/4=19/3
OpenStudy (fouzberzerk):
1/3
OpenStudy (er.mohd.amir):
w=19/3-1/4 tranfer the 1/4
OpenStudy (fouzberzerk):
That comes out to 6 7/12.
OpenStudy (er.mohd.amir):
take LCM and solve it w=19/3-1/4

OpenStudy (er.mohd.amir):
73 divide by 12 get 6 and remainder is 1 so 73/12=6 1/12
OpenStudy (fouzberzerk):
That still doesn't solve my question. I need something that equals 6 1/3
OpenStudy (fouzberzerk):
Whatever, forget about that question.
