Question

3 5\9 + ( - 2 1\4) - ( - 4 5\6) - 5 2\3

Answer 1

3 5/9 + ( - 2 1/4 ) - ( - 4 5/6 ) - 5 2/3 = 32/9 - 2 1/4 + 4 5/6 - 17/3 = 32/9 - 9/4 + 29/6 - 17/3 = 17/36

Answer 2

$3 \frac{5}{9} = \frac{32}{9} = \frac{128}{36} \\ - 2 \frac{1}{4} = - \frac{9}{4} = - \frac{81}{36} \\ - 4\frac{5}{6} = - \frac{29}{6} = - \frac{174}{36} \\ - 5 \frac{2}{3} = - \frac{17}{3} = - \frac{204}{36}$
$\frac{128}{36} - \frac{81}{36} = \frac{47}{36} \\ \frac{47}{36} + \frac{174}{36} = \frac{221}{36} \\ \frac{221}{36} - \frac{204}{36} = \frac{17}{36}$
Ответ 17/36
