Question

(2 целых 1/5 + 14/15) x (-2 целых 1/2)

Answer 1

(2 1/5+14/15)*(-2 1/2)=(11/5+14/15)*(-2 1/2)=(33/15+14/15)*(-5/2)=47/15*(-5/2)=-47/6=-7 5/6

Answer 2

1)2 1/5  +  14/15 = 11/5  +  14/15 = (11 × 3  +  14 × 1)/15 = 33/15  +  14/15 =  47/15 = 3 2/15
2)3 2/15 × (- 2 1/2) = 47/15  ×  ( - 5/2) =  - 47/6 = - 7 5/6
ОТВЕТ : - 7 5/6
