tim phan so co mau khac 1 biet rang tich cua tu va mau la 210 va no co the viet duoc duoi dang so thap phan huu han, co ..................... phan so thoa man
Ta có: \(\frac{a}{b}\left(b\ne1\right)\)
Vì tích của tử và mẫu=210 nên \(a,b\subseteqƯ\left(210\right)\)
\(Ư\left(210\right)=\left\{1;210;2;105;3;70;5;42;6;35;7;30;10;21;14;15\right\}\)
\(\Rightarrow\frac{a}{b}=\frac{105}{2}=\frac{42}{5}=\frac{21}{10}\)
Vậy có 3 phân số thỏa mãn
