Answer 1

t*8/13=28/91*6/7
t*8/13=24/91
t=24/91:8/13
t=24/91*13/8
t=3/7

Answer 2

Выражение: t*(8//13)=(28//91)*(6//7)
Ответ: t*(8//13)-(24//91)=0
Решаем по действиям:1. 28//91=4//132. (4//13)*(6//7)=(24//91)
Решаем по шагам:1. t*(8//13)-(4//13)*(6//7)=0  1.1. 28//91=4//132. t*(8//13)-(24//91)=0  2.1. (4//13)*(6//7)=(24//91)
