Who s going to help me with these questions? 3rd grade

A 1Blockbuster 2Cover the sky with one hand 3Very stingy.

One, two, three is basically not wrong.

I'm not absolutely sure of the four basics, and I don't know what the correct answers are.

These questions are too difficult for third-graders... It's good that I also graduated from Chinese, and I thought about it for a long time.

1.Deafening 2Cover the sky with one hand 3.

1.Scattered 2Lose three and lose four 3 after another 4Three-five in groups of 5 not three not four inch into the foot.

Rampant and domineering, meeting in the water, self-inflicted, unattainable, white and red.

Standing up to the sky, uprooting from home, incomparable, water and sky, wonderful pen and flowers, opening the book is beneficial, and disappearing is very certain!!

1. Earth-shattering, covering the sky with one hand, and not pulling out a hair.

Second, seven scattered and scattered, three and four, one after another, three or five in groups, not three, not four, inch by inch.

3. Rampant and domineering, meeting in the water, self-inflicted, unattainable, black and white.

Fourth, crumbling, far away, deep as the sea, endless, empty.

What do you think of this? If it's good, add a few more points.

A 1Earth-shattering2 Cover the sky with one hand 3 and never pull out a hair.

2. 6 inch in.

One, 1, muffled thunder rolling 2, one hand covering the sky 3, not pulling out a dime.

Divide Xiaodong's number into 3 types, the first is a storybook, the second is a science book, and the third is a story book and a book other than a science book.

There are 58 books that are not storybooks, and this includes science books and books other than the two.

There are 42 books that are not science books, which include story books and books other than the two.

58 + 42 = 100 contains 2 times the number of science books, story books, and books other than the two.

There are 100 science books and story books, so there are (100-60) 2=20 books other than the two.

Then there are 58-20=38 science and technology books.

There are 42-20=22 storybooks.

38+22=60, the answer is correct.

According to the analysis of the title, Xiaodong's books are divided into three categories, story books, science and technology books, and other books, which should be extracted from the text.

Next, use graphics to aid comprehension, draw a large circle, draw two small circles inside, write a story book and a science book, and write other books in the blank part of the big circle.

According to the meaning of the title: other books + science books = 58, other books + story books = 42, science books + story books = 60, here you can use shadows to explain the relationship between several numbers.

So 58 + 42-60 = other books + other books = 2 times other books = 40 books So there are 20 other books, science books = 58-20 = 38 story books = 42-20 = 22 books.

According to the title, there are three kinds of books by Ruo Xiaodong. It is divided into science books, storybooks, and other books. Then it can be calculated according to the known conditions.

Other books: (58 42 60) 2 = 20 books.

Science and technology books: 58 20 = 38 books.

So if there are only three kinds of books, then the number of science books is 38.

From the title, it can be seen that ten other books of science and technology = 58

Storybook ten other books = 42

Tech Book Ten Story Books = 60

The sum of the three forms can be obtained.

2 (science and technology books, 10 story books, 10 other books) = 160

Science and Technology Books Ten Story Books Ten Other Books = 80

That is, a total of 80 books.

So. Other books = 80-60 = 20 (books).

Storybook = 80 - 58 = 22 (copies).

Science and technology book = 80 - 42 = 38 (book).

The answer is as follows, first ask for the total number of books, and then subtract the number of non-science books from the total number of books to get the number of science and technology books.

The weight of an adult Tibetan antelope is given as a range, with a minimum of 35 kg and a maximum of 40 kg, and the question asks about the maximum weight of a wild donkey, which is of course a maximum weight of 40 kg. So.

40 kg x 8 = 320 kg.

1 basket of apples - 1 basket of oranges = 15 kg.

1 basket of pears + 1 basket of oranges = 60 kg.

The sum of the two formulas.

1 basket of pears + 1 basket of apples = 75 kg.

It is the third formula, that is to say, the third formula is the first two formulas pushed out, so this becomes a ternary system of equations, however, there are only two equations, and one equation is missing, which cannot be solved, but if you want to guess, you have to match the number, it is still possible, of course, there can be countless ones, I don't believe you try.

A apple, o orange, p pear.

a-o=15

p+o=60

These two formulas add up to the third formula, that is to say, this 3 yuan equation only gives two valid equations, so the exact value cannot be found, if you are in the third grade of primary school, you should not have learned decimals, then the values should be positive integers.

A basket of apples is 45 kg, a basket of pears is 30 kg, and a basket of oranges is 30 kg.

This question is also called backwards. Barrel B 24 kg + 12 = 36 kg.

A bucket turned out to be 12 + 18 = 30 kg.

Barrel B turned out to be 48-30 = 18 kg.

The boy's birthday is October 2.

Since today is September 19 and 2 (indicated in the picture), the girl's birthday is September 30.

s=2 +2*4=4+8=12 (that is, the area of a square is 2, the area of a rectangle is 2*4, and then add them together to make it the area of a large rectangle).
