`(5+5+5)/(7+7+7)-(5+5)/(7+7)+5/7=?` `1/7` (b) `3/7` (c) `5/7` (d) `(13)/(14)`

1-:(-5)/7= 2/7 (b) 5/7 -2/7 (d) (-7)/5

(-5)/(7)+(-6)/(-7)

2 3/5-:5/7=\ (13)/7 (b) (13)/(25) (91)/(25) (d) (25)/(91)

(5)/(7)+(-12)/(5)=-(12)/(5)+(5)/(7)

If (x)/(y)=(6)/(5), then the value of ((6)/(7)-(5x-y)/(5x+y)) is equal to (a) (1)/(7)( b) (2)/(7)(c)(3)/(7) (d) (4)/(7)

(7x+5)/(5)=7x

A point on the line (x-1)/1=(y-2)/2=(z+1)/3 at a distance sqrt(6) from the origin is (A) ((-5)/7, (-10)/7,13/7) (B) (5/7,10/7,(-13)/7) (C) (1,2,-1) (D) (-1,-2,1)

(5)/(7)times(5)/(7)times(5)/(7)times(5)/(7)

The mean of (5)/(7) and (7)/(5) is
