Question

32,7×3 5/19 -97/12×(-32,7)+32,7

Answer 1

$32.7 \times 3 \frac{5}{12} - 9 \frac{7}{12} \times ( - 32.7) + 32.7 = \\ \\ = \frac{327}{10} \times \frac{41}{12} - \frac{115}{12} \times ( - \frac{327}{10} ) + \frac{327}{10} = \\ = \\ \frac{109}{10} \times \frac{41}{4} + \frac{23}{4} \times \frac{109}{2} + \frac{327}{10} = \\ \\ = \frac{4469}{40} + \frac{2507}{8} + \frac{327}{10} = \\ \\ = \frac{2289}{5} = 457 \frac{4}{5} = 457.8$
