Giải:

Hiệu hai số tự nhiên và số thập phân là 2147,47. Suy ra phần thập phân của số thập phân phải có hai chữ số. Nếu bỏ dấu phẩy của số thập phân đi thì số thập phân sẽ tăng 100 lần và hiệu hai số là 1303. Suy ra số thập phân là số trừ và hiệu số giảm đi chính bằng 99 lần của số thập phân.

Hiệu số giảm đi là:

2147,47 - 1303 = 844,47

Số thập phân đó là:

844,47 : 9 = 8,53

Đáp số : 8,53
