                        a . b = 9 . 9 = 81

Báo cáo sai phạm

\(\frac{2}{3}\)Số tiền sách của em \(=\frac{1}{2}\)số tiền sách của anh tức là:

\(\frac{2}{3}\)Số tiền sách của em = \(\frac{2}{4}\)số tiền sách của anh

Hay là \(\frac{1}{3}\)số tiền sách của em = \(\frac{1}{4}\)số tiền sách của anh

Vậy ta có sơ đồ

Tiền sách của em: |---|---|---|

Tiền sách của anh: |---|---|---|---|

Tổng số tiền sách của em là:

18 900: (3+4) x 3 = 81000 ( đồng)

Tổng số tiền của anh là:

18 900 : (3+4) x 4 = 108 000 ( đồng )

                             Đ/S : Em : 81 000 đồng

                                      Anh: 108 000 đồng.

để cái cân tự cân chính nó thì chính nó phải tự cân mình, tức là cái cân phải tự cân mình, tức là chính nó phải tự cân mình, từ đó suy ra câí cân phải tự cân nó, nhưng chính nó phải được chính cái cân cân, vậy nên cái cân phải cân chính nó thì cái cân mới tự cân chính nó :))
