Question

Пожалуйста помогите решить пример: (2-целых 8/51 - 8/51 ×15,3):(-31/51)

Answer 1

(110/51 - 8/51 * 15,3) : (-31/51) = (110/51 - 8/51*153/10) : (-31/51) = (110/51 - 12/5) : (-31/51) = (-62/255) : (-31/51) = 2/5

Answer 2

1)8/51*15,3=8/51*15 3/10=8/51*153/10=12/5

2)2 8/51-12/5=110/51-12/5=550/255-612/255=-62/255

3)-62/255:(-31/51)=62/255:31/51=62/255*51/31=2/5
