136 nghìn đồng =100 000đ+30 000đ+6 000đ nên 

số tiền 100 000đ cần trả là:100 000:100 000=1(tờ)

số tiền 10 000đ cần trả là:30 000:10 000=3(tờ)

số tiền 1 000đ cần trả là:6 000:1 000=6(tờ)

Vậy cần trả 1 tờ 100 000đ,3 tờ 10 000đ,6 tờ 1 000đ

Bạn cứ hiểu đơn giản rằng:

SP : là điểm mà mọi người ( các tài khoản học sinh thường ) tick đúng cho bạn mỗi khi bạn trả lời đúng 1 câu hỏi.

GP : là điểm mà chỉ khi bạn được các bạn CTV, CTVVIP và các thầy cô trên OLM tick đúng cho câu trả lời của mình thì bạn mới nhận được GP. Ngoài ra, bạn còn có thể nhận GP thông qua việc tham gia các cuộc thi trên diễn đàn hỏi đáp của OLM.

Ta nhận thấy \(\dfrac{9}{10};\dfrac{9}{11};\dfrac{10}{11}\) khi quy đồng có \(MSC=110\)

Để so sánh \(3\) phân số thì ta quy đồng từng phân số sao cho cả \(3\) phân số đều có \(MSC=110\)

Ta có :

\(110:10=11\)

\(110:11=10\)

Quy đồng:

\(\dfrac{9}{10}=\dfrac{9\times11}{10\times11}=\dfrac{99}{110}\)

\(\dfrac{9}{11}=\dfrac{9\times10}{11\times10}=\dfrac{90}{110}\)

\(\dfrac{10}{11}=\dfrac{10\times10}{11\times10}=\dfrac{100}{110}\)

Sắp xếp các phân số đó theo thứ tự từ bé đến lớn , ta được:

\(=>\dfrac{90}{110}\left(\dfrac{9}{11}\right);\dfrac{99}{110}\left(\dfrac{9}{10}\right);\dfrac{100}{110}\left(\dfrac{10}{11}\right)\)

Vậy khi sắp xếp các phân số theo thứ tự từ bé đến lớn ta được:\(\dfrac{9}{11};\dfrac{9}{10};\dfrac{10}{11}\)
