One billion and eighty-seven thousand is written (1000087000), and the number rewritten into billions of units is ( billion ).

6:45 = ( ) (fill in the decimal number) hectares = (87,000) square meters.

3: (15) = 20 )% = 20 (4) = (2) into.

Rotate the (right-angled trapezoidal shape along the long base edge) for one rotation to get the shape (cone above, cylinder below).

On a map with a scale of 1:5000000, the distance between A and B is 5cm, and the actual distance between A and B is (250) kilometers, and if a car can travel the whole distance in 10 hours, then its speed is (25 kilometers per hour).

and 30 is the greatest common factor (5), and the least common multiple is (30).

3 grams of salt dissolved in 100 grams of water, the salt content ( ) in the salt content of 30% brine, the mass ratio of salt to water is (3:7).

5x = 6y, then y of x = (5 out of 6), x is more than y (20)%.

In a square with an area of 5 square secretions, draw a circle with a maximum of 1/4 of a circle, and the area of the circle is ( ) square decimeters.

A piece of steel is 5 meters long, and it takes 3/5 of an hour to sawn it into 50 cm segments, and (4/15) hours if it is sawn into 100 cm long sections.

What a lazy boy!

You should be able to figure it out by yourself! If you don't use your brain often, it will rust!

I'm the wrong word.

The questions in Year 6 are very simple

It's not difficult to think about it! ~

It won't do you any good if you really tell you the answer, you won't learn at all!

If: the sum of the divisor, the dividend, and the quotient is, the quotient is, and the dividend is ( ) If the divisor is, the quotient is ( ).

In 1 division, the sum of the divisor, the dividend and the quotient is, if the quotient is, the dividend is ( ) If the divisor is, the quotient is ( ).

One: a, b, c

Two books: AA, BB, CC, AB, AC, BC

Three books: ABC, AAB, AAC, BBA, BBC, CCA, CCB have a total of 3+6+7=16

The answer is 16+1=17

There are six types of A, AB, AC, B, BC, and C, and you can borrow 1-2 copies or one copy of each of each type (except AA, BB, CC);

a, b, c, 3 + 3 kinds, the remaining ab, ac, bc have 3 + 3 + 3 kinds, a total of 15 kinds, 15 + 1 = 16, so fill in 16

1.The number of white swans is more than that of black swans, accounting for 30% of the number of black swans.

2.Turnover indicated (less this year than last year) accounted for 8% of (last year's) turnover.

3.The output represented (actually increased from the original plan) accounted for 17% of the (originally planned) production

1 4 more than b, a is equivalent to b's (five-quarters).

2.The elder brother is 140 centimeters tall, which is 1 6 centimeters taller than the younger brother, and the younger brother's height is (120) centimeters.

3.A strip of wood is 9 meters long, and 1 4 meters of it is taken away, and 1 4 meters of it is sawn off, for a total of (two and a half) meters.

1.The ratio of number A to number B is 4:5, the ratio of number B to number C is 3:4, and number A is more than number B = (4): 5).

2.If the six (1) class is transferred from 1 10 to six (2) classes, the two classes will be equal in size, and the original ratio of the number of students in six (1) classes to six (2) classes is (11) :(1).

3.（6）/5=：（ 2 ）=3/4：（ 5 ）=4.(The ratio is unchanged when the preceding and subsequent terms of the ratio are multiplied or divided by the same multiple at the same time (except for 0) is called the basic property of the ratio.

（1）：3:5

4): Ratio of the previous and subsequent terms, multiplied or divided by an identical number at the same time, the ratio does not change.

Trains depart at the same time every 50 minutes, 7:00 to 12:00 for a total of 5 hours, that is, 300 minutes, 300 50 = 6, divisible, so at 12:00 at the same time, the last train before 12:00 at the same time at 11:10

1570 cubic centimeters.

Solution: The bottom surface of the cylinder is circular, cut into small fans, and the rectangle is as shown in the figure, and the surface area of the original cylinder is S1=2 R 2+2 Rh After changing the bottom surface, the original cylinder becomes a cuboid, and the bottom area of the cuboid is still r 2 (length is r, width is r), the area of length and height is rh, and the area of width and height is rh

And because the cuboid has 6 faces.

Therefore, the surface area of the cuboid is s2=2 r2+2 rh+2rhs2-s1=2rh=2*r*20=40r=200r=5cm

v = r2h = cubic centimeter.

The most is the area of the two sides of the box.

First, calculate the radius to be 5cm.

Then the volume is 500 cubic centimeters.

If you take equal to, the answer is 1570 cubic centimeters.

Is this really an elementary school question? I don't understand it at all... The point is that I forgot what a factor is.
