a) 351,9 ÷ (-17)=? b) - 62,588 ÷ 62 =? c) -1617,84 ÷ (-321) =?​

Answer 1

Пошаговое объяснение:

а)

351,9 : (-17) = 351 9/10 * (-1/17) = 3519/10 * (-1/17) =

207/10 * (-1/1) = -207/10 = -20,7

б)

-62,558 : 62 = -62 558/1000 * 1/62 = -62558/1000 * 1/62 = -1009/1000 * 1/1 = -1009/1000 = -1,009

в)

-1617,84 : (-321) = -1617 84/100 * (-1/321) =

-161784/100 * (-1/321) = -504/100 * (-1/1) =

504/100 = 5,04
