Gọi 2 số cần tìm là a, b. (a, b\(\in\)Z )
Từ a-b=9
<=> a=b+9
Theo bài toán ta có:
\(\frac{7}{9}a=\frac{28}{33}b\)
\(\Leftrightarrow\frac{7}{9}\left(b+9\right)=\frac{28}{33}b\)
\(\Leftrightarrow\frac{7}{9}b+7=\frac{28}{33}b\)
\(\Leftrightarrow\frac{-7}{99}b=-7\Leftrightarrow b=99\)
Từ b=99 => a=108
Vậy hai số a,b là 99 và 108
Bài này bấm máy tính 570 hoặc 500 là ra đó.
\(\frac{2999997}{6}\)-\(\frac{1999998}{6}\)-\(\frac{999999}{6}\)=0
