Xiao Ming s family lives on the 9th floor, and how many stairs does he need to climb every day to wa

To walk from the first floor to the door, you need to climb 8 flights of stairs;

There is no need to climb stairs on the first floor, one floor on the second floor, and two floors on the third floor. 9-1=8

You must first know the height of each floor of his house, because the number of stairs is different, that is, the number of stairs on each floor is multiplied by 8, and the number on the first floor can be ignored.

When he was on the 1st floor, he didn't count climbing the stairs, and then from the 2nd floor, he needed to climb 8 flights of stairs to the 9th floor, and then arrived at the door.

There is one less condition for this question, how many steps are there on each staircase? The number of steps in our local area is different, some are 3 meters high, and some are shorter, so its step design is different.

Xiao Ming's family had to climb nine flights of stairs to reach his house.

Xiao Ming's home is on the ninth floor, and he walks from the first floor to the door every day, and the community needs 10 stairs.

You need to climb 8 flights of stairs every day, and of course if you have an elevator, you don't need it.

The question he asked was a little more complicated, and it had to be seen how many stairs there were on a floor, and then multiplied by nine.

The answer is 8 percent from the first floor to the 2nd floor, and all 9 minus one to get 8 percent.

You need to climb from the first floor to the ninth floor.

9-1 8 floors of stairs.

According to the property regulations, the elevator is pressed above the eighth floor, so it will take the elevator directly to the ninth floor when it reaches the first floor.

13th floor. Analysis: Climb 3 floors from 1 to 4.

1 to 10 climb 9 floors.

So Xiao Ming climbed to.

to the 13th floor. Xiao Ming climbed to the 5th floor and climbed 5-1=4 floors, and Xiao Hong climbed to the 4th floor and climbed 4-1=3 floors, so Xiao Ming's speed is four-thirds of that of Xiao Hong. When Xiao Hong climbed to the 10th floor, he climbed 10-1=9 floors, and at this time Xiao Ming had already climbed (9*four-thirds), which is the 12th floor, plus the first floor did not need to climb, so at this time he reached the 13th floor.

Definition of addition: The operation of combining two numbers into a single number.

Subtraction: The operation of finding another addition in the sum of two known additions and one of them.

Multiplication: The operation of finding the product of two numbers.

Division: The operation of knowing the product of two factors and one of the factors, and finding the other factor.

Xiao Ming climbed the stairs to the 5th floor, climbing: 5-1=4 floors.

Grandpa climbed to the 4th floor and climbed: 4-1=3 floors.

Xiao Ming climbed to the 9th floor and climbed: 9-1=8 floors.

At this time, Grandpa climbed: 8 4x3 = 6 floors, and Grandpa climbed to: 6 + 1 = 7 floors.

There are two flights of stairs from the first floor to the third floor, so the first floor takes 6 2 = 3 minutes.

Then 1 7th floor has 6 floors, then 3*6=18 minutes.

So it takes 18 minutes, but I don't understand what the stalk is about living on the fifth floor, <>

6 (3 1) 3 (min).

3 (7 1) 18 (min).

A: It takes 18 minutes.

If you count how many floors he climbed, from the first floor to the fourth floor, he climbed 4-1=3 floors, and the first floor climbed to the 10th floor is 10-1=9 floors, so that the speed can be calculated, 6 3=2, that is, 2 minutes per floor, and then 2 times 9=18 minutes, so it takes him 18 minutes to climb from the first floor to the 10th floor.

It takes 6 minutes from the first floor to the fourth floor, so the time required for each floor is 6 4=minutes, so it takes a total of 10 minutes to get to the 10th floor.

From the first floor to the fourth floor, you need to climb 3 flights of stairs, 6 3 = 2 minutes, from the first floor to the tenth floor, you need to climb 9 flights of stairs, 2x9 = 18 minutes, and Xiao Ming needs 18 minutes to get home from the first floor.

From the 1st floor to the 4th floor, it takes 6 minutes to climb 3 flights of stairs, 6 3 = 2 minutes on each floor, and from the 1st floor to the 10th floor, you need to climb 9 flights of stairs, which takes 2*9=18 minutes.

Hello, according to your description.

So Xiao Ming's house is on the 10th floor, and it takes 6 minutes to climb from the first floor to the fourth floor, and according to this calculation, it takes 18 minutes to get from the first floor to his house.

18 (min) Answer: It takes 18 minutes to get from the first floor to his house.

It took 6 minutes to go up to the 3rd floor from the first floor to the 4th floor, 2 minutes to go up each floor, and it took 18 minutes for Xiao Ming's house to walk the 9th floor ladder on the 10th floor.

6 (4 1) x (10 1) = 18 points.

A: It takes 18 minutes to get to his house from the first floor.

Xiao Ming's family lives on the 13th floor, how many flights of stairs did Xiao Ming climb when he returned home from the first floor?

Hello, I am happy to serve you and give you the following answer: Xiao Ming's family lives on the 13th floor, and he climbed 12 flights of stairs from the first floor to get home. Stair climbing is a rewarding exercise, but it's also important to be safe.

The workaround and practice steps are as follows:1Warm up first:

Before climbing the stairs, you should do some warm-up exercises, such as jogging, stretching, etc., to avoid injury. 2.Pay attention to the pace:

When climbing stairs, pay attention to your pace and not too fast to avoid falling down. 3.Pay attention to your breathing:

When climbing stairs, pay attention to your breathing and not rush too quickly to avoid suffocation. 4.Stay safe:

When climbing stairs, pay attention to safety and do not put your hands on the stairs to avoid injury. Radical Eggplant 5Do a good stretch:

After climbing the stairs, stretch well to avoid muscle soreness. Personal experience: Climbing stairs is a beneficial aeroponic exercise, but it is also necessary to pay attention to safety, follow the steps, and do not rush too much to avoid injury.

Summary. If you live on the ninth floor, you need to climb eight flights of stairs.

Xiao Ming's family lives on the ninth floor, and it took him nine seconds to walk from the first floor to the second floor. If the staircase book on every floor is the same. So a minute, will he be able to walk home?

Hello. If you live on the ninth floor, you need to climb eight flights of stairs.

So it took 72 seconds.

More than 60 seconds, so can't.

Xiao Ming's family lives on the 18th floor, and he has climbed 9 floors from the 1st floor, and he has to climb another 8 floors.

Xiao Ming's family lives on the 18th floor, and he has climbed 9 floors from the 1st floor, and he has to climb another 8 floors, (18-1)-9=8 floors. First of all, we use common sense of life to deduce, the ground is called the first floor, that is, the first floor.

If you live on the 2nd floor, you need to climb 1 floor, which is 2-1, if you live on the 3rd floor, then the number of floors you need to climb is 3-1, and the number of floors you need to climb to live on the 18th floor is 18-1=17 floors, and you have already climbed 9 floors, and you need to climb 17-9=8 floors.

Calculation is one of the important contents of mathematical knowledge, mathematical computing ability is a basic mathematical ability, and computing ability is an important foundation for learning mathematics and other subjects.

The Importance of Computing in Mathematics:

In the course of their academic career, computing teaching accounts for a large proportion, and the level of students' computing ability directly affects the quality of students' learning and answers.

Computation plays an important role in mathematics as a whole: some concepts in mathematics need to be introduced through computation. The ideas, steps, and results of solving practical problems in mathematics should also be implemented through calculations.

The teaching of geometry knowledge involves the calculation of perimeter, area, and volume, and the derivation and application of these formulas are also inseparable from calculation.

Knowledge of simple equations, proportions, and statistical charts is also closely related to calculations, which shows that students' numeracy skills are crucial. <>
