A book is 20 pages, read 5 pages a day, and read at least a few days of second grade math

A book has a total of 20 pages? Read five pages a day then 20 5 = 4 days, then it takes at least four days to read, this is a very simple elementary school calculation problem, this second grade of primary school will be completely able to calculate.

It's a question of definite numbers, but what does the title mean at least?

A book is 20 pages, and if you read 5 pages a day, you can read it in 4 days.

A book is 20 pages, and you can read up to 4 pages a day, and it takes at least 4 days to finish it.

Reason: 1) If you read 5 pages a day, you can read 20 pages for 4 days.

2) If you read 4 pages a day, you can read 20 pages for 5 days.

3) If you read 3 pages a day, you can read 20 pages for 7 days.

4) If you read 2 pages a day, you can read 20 pages for 10 days.

5) If you read 1 page a day, 20 pages can be read for 20 days.

6) If the number of pages read per day is different, but all of them are less than or equal to 5, then the number of days to read 20 pages is also greater than 5.

So, read it in at least 4 days.

A book of 20 pages, read 5 pages a day, at least a few days to read? 2nd grade math.

Answer: 20 divided by 5 equals 4 days.

A book is 20 pages, read five pages a day, so how many days does it take to read:

20 5 4 days.

The answer is that it takes 4 days to read the book.

According to the formula: number of pages = number of pages per day * number of days.

Number of days = 20 5 = 4 days.

If it's a second grade.

20 = 5 + 5 + 5 + 5, a total of 4 5s, so at least 4 days.

At least four days to read it, dividing twenty by five equals four, so you can finish it in four days.

5 pages a day, 5 pages on the first day, 10 pages on the second day, 15 pages on the third day, and 20 pages on the fourth day! So it only takes 4 days to watch it!

A book is 20 pages, read 5 pages a day, and you can read it in at least 4 days, calculated as follows 20 5 = 4.

A book has only twenty pages, read five pages a day, it takes a few days to read, this problem is still a question in the second grade of primary school, indicating that this is a basic addition, subtraction, multiplication and division math problem, not a brain teaser, that is, 20 divided by 5, 4 days can be read.

Read at least four days, 20 pages for a book, 5 pages a day, at least 20 5 = 4 days.

After reading it in 4 days, the calculation method:

Therefore, it is necessary to read it in at least 4 days.

In the second grade, I have begun to learn multiplication and division, and I can use 20 5=4 directly, answer: I will read it in at least 4 days.

At the beginning of 20, 5 equals four, so it will take at least four days to read it.

Dear, a book is 20 pages, read 5 pages a day, at least 20 5 = 4 days.

Read five pages a day, a total of 20 pages. Then it is, 20 5 = 4, which means that you can watch it in four days.

Direct division calculations:

20 5 4 days.

At least 4 days to read it.

A book has 20 pages, and you read five pages a day, which is 20 divided by 5 to get 4, and it takes at least 4 yuan to read.

Because after reading 5 6 of the whole book in 5 days, it can be seen that the daily speed of the attack is 1 6 of the whole book, so that after reading 2 days, the remaining 60 pages account for 4 6 of the total number of pages of the whole book, so the total number of pages sought is 60 (4 6) = 90 pages.

60 2 5 (Silver Beam 5 6).

180 pages. A: The book is 180 pages long.

I read 5 6 of this book for five days, so I read 1 6 of this book every day, and I read 60 pages of this book for two days, so this book has 60 (1-2 6) = 60 3 2 = 90 pages.

I read this book for 60 pages and read it for 4 days. I bend Jane to read 60 4=15 pages a day. He read it for another 5 days. 5 15 = 75 pages of pure example, I read 75 pages of buried pants. The book has 75 + 60 = 135 pages. The book has 135 pages.

Because I watched a total of 5 6 in 5 days, I watched 1 6 on average, and I watched 2 6 in two days, and there were 4 6 left, so there were 60 6 = 90 pages in total.

I read 60 pages in 4 days, and I read 60 pages 4 = 15 pages a day, and he read them for another 5 days, 5 15 = 75 pages, and I read 75 pages in total, and there are 75 + 60 = 135 pages in this book, and there are 135 pages in this book.

I've read 60 pages of that book. I read 60 pages a day, and he read it for five days. 5 pages in this book. The state book is 135 pages long.

Pickpocketing 200-62) 6

23 (Dan stool page mold this brigade).

A: On average, I read 23 pages a day

8 10 18 pp.

A: I read a total of 18 pages in two days.

Analysis Read 8 pages a day, just read it in 3 days, early touch according to the meaning of multiplication, this book has a total of 8 3 pages, if you read 6 pages a day, according to the meaning of division, divide the total number of pages by the number of pages read per day, that is, you can read it in a few days

Answer: 8 3 6

4 (days) Answer: You can read it in 4 days

Comments: The key to completing this question is to find out the total number of vertical pages according to the work efficiency and working hours=workload

Start reading from page 41, 15 and 25 are used in the question bridge and 60 are not used, and a total of 40 pages of Qin Debate are read in two days, and the first respectful style of the Min is counted: 15 + 25 = 40 (pages), so on the third day, you should start reading from 40 plus 1 page.

The title of this cover is very simple, just add the number of pages of the two.

25 + 20 = 45 (pages).

A: I read a total of 45 pages in two days.

I read 25 pages on the first day, 20 pages on the second day, and a total of 45 pages.

24-5=19 (pages).

Answer: Chi Li read 19 pages of the second disturbance.

17 (pages) A: There are 17 pages left to read.
