`(2)/(5)times((-3)/(7))-(1)/(6)times(3)/(2)+(1)/(14)times(2)/(5)`

[((-2)/(-3))times(1)/(5)]times((-2)/(7))=((-2)/(-3))times[(1)/(5)times((-2)/(7))]

(5)/(4)times(2)/(6)+(3)/(2)times(2)/(1)+(3)/(6)times(3)/(2)

Using appropriate properties find.(i) -(2)/(5)xx(3)/(5)+(5)/(2)-(3)/(5)xx(1)/(6)( ii) (2)/(5)xx(-(3)/(7))^(2)-(1)/(6)xx(3)/(2)+(1)/(14)xx(2)/(5)

(2)/(5)x-(3)/(7)-(1)/(14)-(3)/(7)times(3)/(5)

-(2)/(3)times(3)/(5)+(5)/(2)-(3)/(5)times(7)/(6)

((-4)/(3))times(1)/(2)+((-4)/(3))times((-7)/(5))

solve it : (ii) (-3)/(5)times(-3)/(5)times(-3)/(5)times(-3)/(5) (iii) (-9)/(2)times(4)/(2)times(-4)/(2)times(-4)/(2)times(-4)/(2)times(-4)/(2) (iv) (-5)/(3)times(-5)/(3)times(-5)/(3)times(-5)/(3) (v) (-6)/(2)times(-6)/(2)times(-6)/(2)times(-6)/(2)times(-6)/(2)

Proved that (2)/(3)times[(-6)/(7)times(4)/(5)]=[(2)/(3)times(4)/(5)]times((-6)/(7))

(4(2)/(3)times(9)/(14)+5(1)/(6)times2(2)/(5)) of 417(7)/(8) =
