First of all we must find %1
For This
İf %24 of 215, %1=?
$${\frac{{\mathtt{215}}}{{\mathtt{24}}}} = {\mathtt{8.958\: \!333\: \!333\: \!333\: \!333\: \!3}}$$
İf %1=8.958333, What is the %100
Question of us wants it, What is the %100
İf 1 piece is 8.958333, What is the 100 piece
For This
$${\mathtt{8.958\: \!333}}{\mathtt{\,\times\,}}{\mathtt{100}} = {\mathtt{895.833\: \!3}}$$
The Result is 895.83¯
