`6/6 ; 8/10 ; 12/18 ; 11/8`
So sánh `8/10` và `12/18` vì `6/6=1; 11/8>1` (tử lớn hơn mẫu)
`8/10=4/5=12/15`
`12/18=2/3=10/15`
`=>10/15<12/15` hay `12/18<8/10`
Vậy phân số nhỏ nhất trong dãy là `12/18`
Đáp án:
`12/18`
Giải thích các bước giải:
`6/6=1`
`11/8>1`
Ta có so sánh `2` phân số `8/10` và `12/18`
`8/10=4/5`
`12/18=2/3`
Quy đồng :
`4/5=12/15`
`2/3=10/15`
Mà `12/15>10/15` hay `8/10>12/18`
Vậy phân số nhỏ nhất là `12/18`

Read the following passage and mark the letter A, B, C or D to indicate the correct answer to each of the questions. I get a lot of letters at this time of year from many people who have a cold which won’t go away. There are many different stories about how to prevent or cure a cold. That’s why it is often difficult to know what to do. We know that colds are rarely "dangerous", except for weak people such as the elderly or young babies. These people are always uncomfortable and usually MOST unpleasant. Of course, you can buy a lot of medicines. They will help to make your cold less unpleasant. However, you must remember that nothing can actually cure a cold or make it go away faster. Any strong medicine used to make you feel better could be dangerous if you are already taking drugs for some other illness. Thus, check with your chemist or doctor to see whether they are all right for you. And remember they might make you sleepy. Please don’t try to drive if they do! Lastly, whatever you may be told about magic foods or drinks, the best answer is to keep yourself strong and healthy. You’ll have less chance of catching a cold. And if you do, it shouldn’t be so bad. 17. The writer of the passage wants _______. A. to complain about his/ her health B. to give general advice C. to write in an amusing way D. to persuade people to have more foods and drinks 18. Colds are ______________. A. unpleasant B. not dangerous at all C. very dangerous D. usually fatal 19. What is the key to avoid catching a cold?
