20 = 1+2+3+5+9 = 0,12359

ta co neu xoa chu so 0 o so lon ta dc so be \(\Rightarrow\)so lon gap 10 lan so be\(\Rightarrow\)10a=b

goi so be la a goi so lon la b . ta co :

10a+b=858 . hay b+b=858

2b=858

b=858/2=429

a=42.9

chac la sai vi cung lau rui mk chua lam . chi can co bai la dc rui !!!

nếu xóa chữ số 0 ở tận cùng số lớn được số bé nghĩa là số lớn gấp 10 lần số bé . Coi số bé là 1 phần số lớn là 10 phần ta có

số bé = (858/11)*1=78

số lớn = 858-78=780
