Answer» 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, 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. The given expression: $(\begin{array}{l} 1\frac{1}{4} + 2\frac{1}{5} \times \frac{5}{8} \div 4\frac{1}{2} = ?\\ \Rightarrow \frac{5}{4} + \frac{{11}}{5} \times \frac{5}{8} \div \frac{9}{2} = ?\\ \Rightarrow \frac{5}{4} + \frac{{11}}{5} \times \frac{5}{8} \times \frac{2}{9} = ?\\ \Rightarrow \frac{5}{4} + \frac{{11}}{{36}} = ?\\ \Rightarrow \frac{{\LEFT( {5 \times 9} \right) + 11}}{{36}} = ?\\ \Rightarrow \frac{{45 + 11}}{{36}}\\ = \frac{{56}}{{36}}\\ = \frac{{14}}{9} = 1\frac{5}{9} \END{array})$ |
