6 класс N 416 помогите плиз​

Answer 1

1) $-\frac{25}{28} + (-\frac{18}{35} ) =- \frac{25}{28} - \frac{18}{35} =\frac{-125-72}{140} = -\frac{197}{140} = -1\frac{57}{40}$

2)  $-\frac{19}{60} + (-\frac{11}{24})= -\frac{19}{60} -\frac{11}{24} = \frac{-456-660}{1440} =-\frac{1116}{1440} = -\frac{31}{40}$
