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
Vì nếu chuyển dấu phẩy của nó sang bên trái 1 hàng thì số đó giảm đi 10 lần
Và nếu chuyển chuyển dấu phẩy của nó sang bên phải 1 hàng thì số đó tăng thêm 10 lần
ta có sơ đồ bn tự vẽ nha,số A là 10 phần,số B là 1 phần và số C là 100 phần
Tổng số phần bằng nhau là : 1+10+100=111(phần)
Số A là :221,778 : 111 x 10 = 19,98
Đ/S:19,98
