Vì tổng của 1 số tự nhiên và 1 số thập phân là 82,34 nên số thập phân có 2 chữ số ở phần thập phân

Số thập phân có 2 chữ số ở phần thập phân nên quên dấu phẩy tức là tăng số đó lên 100 lần. Như vậy tổng đã tăng thêm 99 lần số đó.

Suy ra số thập phân là (1106–82,34):99=10,34

Số tự nhiên là 82,34–10,34=72.

Đáp số: 72 và 10,34.

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

Số A, B,C số nào nhỏ nhất

Đúng rồi số B

B kém A 10 lần

B kém C 100 lần 

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

B= 1,998 sÔ A LÀ 19,98

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
