`(6)1/3-:3/10` of `11/9+5/6`

Which is greater: (5)/(6) of (3)/(4) or (3)/(12) of (11)/(9) ?

Simplify: 1'1/11 + 2'2/11 + 3'3/11 + 4/11 + 5/11 + 6/11

21 1/9 -: [5/9 of { 3 1/(27) -(6-bar(1/3-1/6))}]

Solve the following equation : 11 -: 3 + (1)/(9) - 5 xx 6 (1 xx (1)/(6) ) =?

The expression (5(5)/(8))/(6(3)/(7)) of (6(7)/(11))/(9(1)/(8))-:(8)/(9)(2(3)/(11)+(13)/(22)) of (3)/(5) equals (a) 1 (b) (1)/(2)( c) (7)/(9)( d) (5)/(12)

Show that sqrt3 =1+ 1/3 +( 1/3 ).( 3/6 )+( 1/3 ).( 3/6 ).( 5/9 )+.......

How many such 6s are there in the following number series, each of which is immediately preceded by 1 or 5 and immediately followed by 3 or 9 ? 2 6 3 7 5 6 4 2 9 6 1 3 4 1 6 3 9 15 6 9 2 3 1 6 5 4 3 2 1 9 6 7 1 6 3 1) None 2) One 3) Two 4) Three 5) None of these

Simplify: [(2 10/27))^(-2/3) ÷ (11 1/9))^(-0.5)] +[(6.25)^(0.5) ÷ (-4)^(-1)]
