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

Solve : ( c) 7/7 - 5/7

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

Simplify (7)/(7)-(5)/(7)

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

Solve: 7/7 - 5/7

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

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

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)

Find the sum of each of the following infinite geometric series, if it exists : (4)/(7) - (5)/(7^(2)) + (4)/(7^(3)) - (5)/(7^(4)) + (4)/(7^(5)) - (5)/(7^(6)) +…oo
