The number of students in the fifth grade class of a school who participated in the cleaning was 1 4 who did not participate, and then 2 students took the initiative to participate, and the actual number of students who participated was 1 3 of the number of people who did not participate.

Solution: Fifth graders are divided into two parts: those who participate in the cleaning and those who do not.

When two more students took the initiative to participate, the number of people who participated in the cleaning increased and the number of people who did not participate in the cleaning decreased, both of which changed, while the total number of fifth graders remained the same. The total number of fifth-grade students is regarded as unit "1", and the original participation in the general cleaning accounted for 1 5 of unit "1", and now the participation in the general cleaning accounts for 1 4 of unit "1", so 2 students account for unit "1" (1 4-1 5).

2 (1 4-1 5) = 40 (person).

1] The velocity of A and B is x, y

3 hours and 30 minutes = hours.

2x+2(x+y)=28

Solve the system of equations to obtain:

x=6,y=2

A speed is 6 km/h, B is 2km/h.

Let the hundred, ten, and single digits be x, y, and z respectively

y=x+z ①

y-z=2 ②

100z+10y+x=100x+10y+z+99 and combined, x=2, y=z+2 are brought in respectively.

Get z=3, so y=z+2=3+2=5

1.Solution: Let the velocity of A be x km, and the velocity of B be y km 4x+2y=28

After that, you'll do it. Remember to use curly braces, it's too cumbersome to put curly braces on the web page, so I'm useless.

2.Solution: Let the single digit be x, the ten digit be y, and the hundred digit be zx+z=y y-x=2 100x+10y+z-(100z+10y+x)=99

I don't know if you've ever learned to set an equation with 3 unknowns, but that's the fastest way I can think of it.

That's right, if the cube of iron is all submerged in the water, you can divide the volume of the cube by the bottom area of the cuboid to get the height of **, the water depth is the sum of the height of ** and the original height, the child did not make a mistake, but the format can be written more neatly.

Wrong. The water depth should be 25 cm.

Incorrect, because the units are not uniform, one is a decimeter and the other is a centimeter.

The salesman exchanged a 5 yuan yuan and a 5 jiao yuan for 28 RMB with 1 yuan and 1 jiao in face value. Solution: There are x sheets of 1 yuan and (28-x) sheets of 1 corner.

Answer: There are 3 cards for one yuan and 25 cards for one corner.

1.Xiaomi drew 2 circles with a ring object. What is the circumference of these two circles?

Circumference cm. Circumference cm.

What fraction of the circumference of the inner circle is the circumference of the outer circle? (The inner circle is 3 cm in diameter) (the outer circle is 6 cm in diameter).

2.The minute hand is 5 cm long. How long does the tip of the needle travel in 1 hour?

Centimeter. 3.A toy race car has a wheel radius of centimeters, a speed of 4,000 revolutions per minute, and a race distance of 500 meters. Will this car make it to the finish line in 1 minute?

62800 cm.

628 meters and 500 meters.

This car can reach the finish line in 1 minute.

1: Circumference of the company c=2 r inner circle radius = 6 outer circle straight blind diameter 6cm? That is, a grinding macro scum is a circle, if the radius is 6cm, the circumference is =12, the ratio of the circumference of the two circles = 6, 12=1, 2

2: One hour The minute hand goes exactly one full circle for a circle, and the distance is the circumference of the circle c=2 x5=10.

3: The length of the wheel is 2 minutes and the distance traveled is s= 4000x5 = 20000 cm, and the length of the wheel is 200, so it is 628 >500
