I like this math problem :>*
Find the greatest natural number m such that:
12/17 < 8/5+m < 21/23
\(\frac{12}{17}<\frac{8}{5}+m<\frac{21}{23}\)
\(m=\frac{8}{5}-\frac{21}{23}\) - 1\(m=-\frac{36}{115}.\)
12/17<8/5+m<21/23
=>-76/85<m<-79/115
ta thấy không có số nguyên nào thuộc khoảng từ -76/85 đến -79/115
=>không tìm được m
