All heroes in the world, help!

I'd better give you a question. I don't have a textbook

The price of a science and technology book is 1.5 yuan less than twice that of a story book, and that of a science and technology book is 13.5 yuan. How much cheaper is a story book than a science and technology book?

(13.5 + 1.5) △ 2 = 7.5 (yuan)
13.5-7.5 = 6 (yuan)

When a car goes from place a to place B, the ratio of the speed in the first half of the journey to the speed in the second half of the journey is 5:4, so the ratio of the time in the first half of the journey to the speed in the second half of the journey is 5:4______ ．

Let the whole journey be 9 copies, 5 copies in the first half of the journey, and half of the journey be 9 △ 2 = 4.5 copies, (5-4.5) △ 5, = 0.5 △ 5, = 110. Let the half of the journey be "1", and the ratio of the first half of the journey to the second half of the journey (1 − 110): (1 + 110) = 9:11. A: the ratio of the first half of the journey to the second half of the journey is 9:11

1 km =? M =? Decimeter =? Cm =? Mm

1 km = 1000 m = 10000 decimeters = 100000 cm = 1000000 mm

Reverence for life
It was a very long afternoon in summer. At first, I was reading a book by a lake in Indiana. Suddenly, I found that some trees by the lake were scattering some big white fibers, big clumps, like cotton, some floating on the grass, some floating into the lake. I didn't pay much attention at that time. I just thought it was the wind that brought the big fibers, Gradually, I found that the situation was just amazing. Hours later, the trees were still drifting, and the small clouds seemed like an infinite cloud bank. All afternoon, all night, it was that kind of thing. The next day, it was exactly the same, and I was surprised and shocked, When I was in primary school, I knew that there was a kind of seed that was delivered by wind and fiber, but I only knew the answer to a test question. I saw it a few days ago, and felt a kind of admiration and awe. It was almost the first time that I met life - though it was a plant. I felt that the cloud like seed strongly collided with something at the bottom of my heart, I can't help but be moved by the luxury of life, the luxury and the investment regardless of cost. Maybe only one seed is enough to make a tree, but the creator is willing to do such a thrilling feat. I am still thinking about the soft water of the lake. I don't know which one of the seeds by the lake has become a small tree? However, I know that one has grown up. The seed once met a piece of land, which became popular in a passing heart Canyon, and taught her how to revere life
Outside the window
From the window of my bedroom, you can see a tall hibiscus tree. In the uneven spring, the red spots are charming. It affects my inspiration and stirs up my literary thinking. As time goes by, I regard this "neighbor" standing across the window as my confidant
However, one morning, I pushed the window and looked, suddenly found that last night's wind and rain had denuded it beyond recognition. Immediately, a kind of sadness of "flowers falling" swept over my heart! I can't help feeling: I stumbled on the road of life, after several twists and turns, several vicissitudes, and lost many beloved friends again and again, life is just like the flowers that go with the wind?
Once, when I came back from the countryside, I felt that the indoor air was a little dull, so I inadvertently opened the window and suddenly felt a light in front of my eyes: a red triangle plum tree was reflected in my eyes, and it was frozen in the background of the setting sun, Why didn't you find this sprouting unyielding life?
Yes, the last petal of Hibiscus has withered, and people's praise for it has been forgotten in the memory of the past. However, the triangle plum has grown up, and the flaming red shows the change and continuation of life. Who can say that loss and gain are not a symphony?
I have been standing in front of the window for a long time and deeply realized that there is no unchanging scenery in life. As long as your heart is always facing the sun, you will find that every morning there will be a beautiful and hazy vision spinning and rising in front of your window, and the world will always convey the prelude of hope
These two articles are both praises of life, which are revealed by the unremitting day and night of the seeds scattered by trees, and by the blooming and falling of hibiscus and bougainvillea
In both articles, the author's "surprise" in [a], the author's surprise is () & nbsp;; in [b], the author's surprise is ()
Based on the above answers, the content of "thrilling feat" in [a] is () & nbsp;; the content of "surprise" in [b] is ()
According to the contents of the two essays, the following questions are answered respectively: (1) people have been exposed to all kinds of life since they were born, but why does the author of article a say "it's almost the first time to meet life?" (2) the withering and opening of flowers are purely a natural phenomenon, why does the author of article B say "sprouting unyielding life"“
These two articles both describe and praise life. There are similarities and differences between them. Please point out them respectively. (1) similarities () (2) differences: [(a)] () & nbsp; [(b)] ()
After reading this article, please talk about your understanding of life

1. The essence of life, the alternation and continuation of life
2. Life is a luxurious, luxurious and no cost investment, and it sprouts unyielding life behind the falling yellow
3. The seeds of trees are scattered to the lake and grassland day and night by life. Under the destruction of the storm, hibiscus has withered, while Bougainvillea has blossomed like a flame
4. Because I didn't care about all kinds of life forms and the essence of life before, and didn't think about the meaning of it. This time I saw the flying catkins of trees, and I saw the connotation of life for the first time. 2. Because the author thought of the fall of some lives from the erosion of hibiscus flowers by wind and rain, and the rebirth of some lives from the opening of triangle plum, From this we can see the alternation and continuation of life
5. Although these two articles are all about life with plants, neither of them refers to the concrete existence, but the vitality of life itself. ② (a) through the flying catkins of trees, what they write is the "luxurious, luxurious, regardless of cost investment" of life; and (b) through the withering and opening of flowers, what they write is the change and continuation of life
6. Cherish life, love life, enhance life consciousness, and establish correct outlook on life, life and values

The least common multiple of 15 and 20 () the least common multiple of 35 and 42 () the least common multiple of 8, 24 and 36 () the least common multiple of 45, 60 and 75 ()

The least common multiple of 15 and 20 (60)
The least common multiple of 35 and 42 (210)
Least common multiple of 8, 24 and 36 (120)
Least common multiple of 45, 60 and 75 (900)

List the proportion formula and solve the proportion (the ratio of 5 / 4 to 8 is equal to the ratio of 2 / 5 to x)

5 / 4: 8 = 2 / 5: X
5 / 4 x = 8 × 2 / 5
5 / 4 x = 16 / 5
X = 16 / 5 × 4 / 5
X = 64 / 25
