Помогите -2,4-(5,6-(1,75+(-2 1/6 + 5 1/4)

1) $-2 \frac{1}{6} +5 \frac{1}{4} =-2 \frac{2}{12} +5 \frac{3}{12} =3 \frac{1}{12} = \frac{37}{12}$
2)1,75+ $\frac{37}{12} = \frac{7}{4} + \frac{37}{12} = \frac{21}{12} + \frac{37}{12} = \frac{58}{12} = \frac{29}{6}$
3) $5,6- \frac{29}{6} = \frac{28}{5} - \frac{29}{6} = \frac{168}{30} - \frac{145}{30} = \frac{23}{30}$
4) $-2,4- \frac{23}{30} =- \frac{24}{10} - \frac{23}{30}= - \frac{72}{30} - \frac{23}{30} =- \frac{95}{30} =-3 \frac{5}{30}=-3 \frac{1}{6}$
