" D- "(2)/(9),(2)/(3),(8)/(21)

Arrange the following in descending order : (i) (2)/(9),(2)/(3),(8)/(21) (ii) (1)/(5),(3)/(7),(7)/(10)

Write each of the following sets in set- builder form : D = {(1)/(2),(2)/(3),(3)/(4) ,….(8)/(9) }.

(-4)/(7)+(2)/(9)+(-5)/(4)+(8)/(21)

(2x-9)/(7)+(2x)/(3)=(8x-1)/(21) What value of x is the solution of the above equation?

Find the value of 1-((1(2)/(3))/(3(1)/(2))+(1(1)/(6))/(3(1)/(2)))* a) (3)/(20) (b) (4)/(21)(c)(8)/(21) (d) (13)/(21)

{:(18,21,24),(3,9,3),((6)/(21),(4)/(26),(8)/(?)):}

Simplify: ((4)/(7)+(-8)/(9) +(-5)/(21) +(1)/(3)) .

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 :
