(iii) ((-7)/(18) x (15)/(-7)) - (1 x 1/4) + (1/2 x 1/4)`

(iii) ((-7)/(18)xx x(15)/(-7))-(1xx1/4)+(1/2xx1/4)'

Simplify : ((-7)/(18)xx(15)/(-7))-(1xx1/4)+\ (1/2xx1/4)

Simplify :((-7)/(18)x(15)/(-7))-(1x(1)/(4))+((1)/(2)x(1)/(4))

((2)/(3)x+4)((3)/(2)x+6)-((1)/(7)x-1)((1)/(7)x+1)

2(x-4)/((x-1)(x-7))>=(1)/(x-2)
