Answer 1

Ответ:

$1\dfrac{17}{24}$

Пошаговое объяснение:

$-5\dfrac{3}{8}+4\dfrac{5}{6}-\bigg (-2\dfrac{1}{4} \bigg )=-5\dfrac{9}{24}+4\dfrac{20}{24}+2\dfrac{6}{24}=6\dfrac{26}{24}-5\dfrac{9}{24}=1\dfrac{17}{24};$

Answer 2

Ответ:

$- 5 \frac{3}{8} + 4 \frac{5}{6} - ( - 2 \frac{1}{4} ) = - \frac{43}{8} + \frac{29}{6} + \frac{9}{4 } = \frac{ - 129 + 116 + 54}{24} \\ = \frac{41}{24} = 1 \frac{17}{24} = 1.7083$
