(5)/(8)+(1)/(2)times((5)/(8)-(6)/(16))=

What should come in the place of question mark (?) in the following questions ? 1(1)/(4) +1 (5)/(9) xx 1(5)/(8) + 6(1)/(2) = ?

5(5)/(6) -3(8)/(9) -? =1

The value of (5^((1)/(4))-: (3)/(7)"of"(1)/(2)) -: (5(1)/(9)-7(7)/(8)-: 9 (9)/(20)) xx(11)/(21)+ (2-: 2 "of" (1)/(2)) is :

(5)(5)/(6)-3(8)/(9)-?=1
