`7/8+3/4(1/2)2/3-1/3)`

If the expression 2(1)/(2) of (3)/(4)xx(1)/(2)-:(3)/(2)+(1)/(2)-:(3)/(2)[(2)/(3)-(1)/(2) of (2)/(3)] is simplified,we get (a) (1)/(2) (b) (7)/(8)(c)1(5)/(8) (d) 2(3)/(5)

(7)/(8)-(3)/(4)+(1)/(2)=(7-3+1)/(8)=

Simplify : (2(3)/(4))/(1(5)/(6)) +7/8 xx(1/3 + 1/4) + 5/7 + 3/4 of 3/7

(7)/(8)-:(7(1)/(2)-5(1)/(6)-:2(3)/(4))+4(1)/(2)

Simplify (i) {(1/3)^(-2) - (1/2)^(-3)} -: (1/4)^(-2). (ii) (5/8)^(-7) xx (8/5)^(-5).
