Directions(Q.1 to Q.10 ):

What will come in place of question mark (?) in the given questions?

$left( {4frac{2}{3} + 3frac{4}{9} + 6frac{5}{9}} ight) div ? = 12$

$left( {4frac{2}{3} + 3frac{4}{9} + 6frac{5}{9}} ight) div ? = 12$

$Rightarrow left( {4 + 3 + 6 + frac{2}{3} + frac{4}{9} + frac{5}{9}} ight) div ? = 12$

$Rightarrow left( {13 + frac{{6 + 4 + 5}}{9}} ight) div ? = 12$

$Rightarrow left( {13 + frac{{15}}{9}} ight) div ? = 12$

$Rightarrow left( {13 + frac{5}{3}} ight) div ? = 12$

$Rightarrow left( {frac{{39 + 5}}{3}} ight) div ? = 12$

$Rightarrow left( {frac{{44}}{3}} ight) div ? = 12$

$Rightarrow ? = frac{{44}}{{3 imes 12}} = frac{{11}}{9} = 1frac{2}{9}$
