Ta thấy trong 3 số thì số B là nhỏ nhất

B kém A 10 lần

B kém C 100 lần 

Tổng A+B+ C = 100 x B+ B + 10 x B = 111 x B = 221,778

B= 1,998 nên số A là 19,98

số C là: 199,8

B kém A 10 lần

B kém C 100 lần 

A 10 phần ; C 100 phần ; B 1 phần

tổng số phần bằng nhau : 100 + 10 + 1 = 111 phần

số thập phân A là : 221,778 : 111 x 10 = 19,98
