[tex]1\frac{2}{5} :(2\frac{4}{15}-3\frac{1}{5} )= -1,5[/tex]
[tex]1)2\frac{4}{15} -3\frac{1}{5} = -3\frac{3}{15}+ 2\frac{4}{15} = -2\frac{18}{15}+2\frac{4}{15} =-\frac{14}{15}[/tex]
[tex]2)1\frac{2}{5} :(-\frac{14}{15} )=\frac{7}{5} :(-\frac{14}{15})= -(\frac{7*15}{5*14} )=-\frac{3}{2} =-1\frac{1}{2} =-1,5[/tex]
Пошаговое объяснение:
1) 2. 4/15 - 3. 1/5 = 2. 4/15 - 3. 3/15 =
2. 4/15 - 2. 18/15 = -14/15
2) 1. 2/5 : (-14/15) = 7/5 * (-15/14) =
1/1 * (-3/2) = -3/2 = -1. 1/2
