Bài 4: Gọi số cần tìm có dạng là \(\overline{2ab}\)

Nếu xóa chữ số 2 đó đi thì được số mới bằng 1/5 số cần tìm nên ta có:

\(\overline{ab}=\frac15\times\overline{2ab}\)

=>\(\overline{2ab}=5\times\overline{ab}\)

=>\(200+\overline{ab}=5\times\overline{ab}\)

=>\(4\times\overline{ab}=200\)

=>\(\overline{ab}=50\)

Vậy: Số cần tìm là 250

\(\frac{37.13-13}{24+37.12.\left(x-2\right):5}=16\)
