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, and in the BRACKET, 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, $(3\frac{2}{5} \times 12\frac{5}{8} - 2\frac{1}{5} \times 5\frac{1}{4} = ?)$ ⇒ ? = 17/5 × 101/8 - 11/5 × 21/4 ⇒ ? = (1717/40) – (231/20) ⇒ ? = (1717 – 462) /40 ⇒ ? = 1255/40 ∴ ? = $(31\frac{3}{8})$ |
