số lớn nhất có hai chữ số là 99

ta có sơ đồ

số thứ 1 :vẽ 4 phần

số thứ 2 :vẽ 5 phần

tổng số phần bằng nhau là

5+4=9

số thứ nhất là

99:9x4=44

số thứ 2 là

99-44=55

Gọi 2 số cần tìm là a, b 

Theo bài ra ta có 

a+b=99

\(\frac{a}{b}=\frac{4}{5}\Rightarrow a=\frac{4}{5}.b\) 

Thay a = 4/5.b vào  a+b=99 ta có

4/5.b + b =99

=> b =55

=> a =44

số lớn nhất có 2 chữ số là: 99

số bé : ( 4 phần )

số lớn : ( 5 phần )

tổng số phần bằng nhau là:

     5 + 4 = 9 phần

giá trị một phần là:

     99 : 9 = 11

số bé là:

     11 x 4 = 44

số lớn là:

     99 - 44 = 55

đ/s số bé ; 44    số lớn : 55
