Follow BODMAS rule to solve this question, as per the order given below, Step - 1 - Parts of an equation enclosed in 'Brackets' must be solved first, and in the bracket, the BODMAS rule must be followed, Step - 2 - Any mathematical 'Of' or 'Exponent' must be solved next, Step - 3 - Next, the parts of the equation that contain 'Division' and 'Multiplication' are calculated, Step - 4 - Last but not least, the parts of the equation that contain 'Addition' and 'Subtraction' should be calculated. Given expression is, $\left[\frac{5}{9}+\frac{3}{81}\div\frac{85}{120}\right]\times\frac{204}{279}$ $\left[\frac{5}{9}+\frac{8}{153}\right]\times\frac{204}{279}=\frac{31}{51}\times\frac{204}{279}=\frac{4}{9}$ ⇒ Square root of (4/9) = √(4/9) = 2/3
