The decimal point of a number is 198 greater than the original number after moving two decimal place

The original decimal point is moved to the right by two places, which is equivalent to the number expanded by 100 times, and the number is expanded by 100 times and is larger than the original number by 198, according to the title, we can know that if the original number is x, the new number after the decimal point is moved to the right by two places, which obtains: 100x-x=198

Solution: 100x-x=198

99x=198

x=198÷99

When solving the equation with x=2, you should pay attention to the alignment of the equal signs up and down, I don't know if you understand. If you have any questions, pay attention to Luoyang Education Baijia.

The original number is 2, and the number after the decimal point is moved to the right by two places is 200.

The decimal point of a number is 198 larger than the original number after moving two decimal places to the right, and moving two decimal places to the right is 10 times larger, which is 9 times larger than the original number, so the original number is: 198 9 = 22.

A decimal point is shifted to the right by 2 places and expanded to 100 times, so it is.

100x-x=198, the solution is x=2, and the original number is 2.

If the number is a, moving the decimal point to the right by two places is a hundredfold increase.

From this, the equation a*100=a+198; a=when the decimal point is moved two places to the right, it becomes 200;

The decimal point of a number is moved to the right by 2 places, expanding to 100 times the original number.

The original number is 2

The decimal point of a number is moved to the right by two places, and the number is expanded by 100 times, and the difference obtained by subtracting the original number from the expanded number is equivalent to 99 times the original number, so 198 is 99 times the original number, then this number is 198 99 = 2, and the original number is 2.

Let the original number be x, and move the decimal point to the right by two places, which means that it is expanded by 100 times, so it becomes 100x. According to the equation 100x-x=198, solve the equation x=2. So the original number is 2.

Move the decimal point two places to the right, and the number expands by a factor of 100, which is 99 times greater than the original number, which is 99 times 198, and all the original numbers are 198 (100-1)=2.

Moving the decimal point of a number to the right by two places is 100 times the original number. After expanding 100 times, it is 198 more than the original, that is, 100 times more than this number is 198, and subtract this number from 100 times this number, that is, 99 times this number is 198, and this number is 198 (100-1)=2.

Moving the decimal point to the right by two places expands by a factor of 100, i.e. by a factor of (100-1) over the original number.

The original number is 2

When a number moves its decimal point to the right by two places, the original number expands by 100 times, which is 99 times more than the original number, and 99 times is 198, then the original number is: 198 99 = 2. You see, if you want to expand 2 by 100 times, isn't 200 more than 2 198, so the original number is 2.

The decimal point is moved to the right by two digits and expanded by a factor of 100, 99 times the original number, which is 198, and all original numbers are 2

Move the decimal point two places to the right, and the original number expands by a factor of 100, to 99 original numbers, 198 (100-1) 2

The original number is 2

Solution: Moving the decimal point to the right by two places expands by 100 times, so it can be obtained by column.

Answer: The original number is 2.

This question can be done like this:

The original number was 22

Moving two places to the right is 100 times larger, which is 99 times more than the original number.

So the original number is: 198 (100-1).

The original number is 2

The original number is 2Solution:

Moving the decimal point of 2 to the right by 2 places is a 100-fold expansion, or 200.

200-2 198, in line with the title.

Moving the decimal point to the right by two places results in a new number that is 100 times the original number. Or that the new number is 100-1 = 99 times larger than the original number.

Original number = 198 (100-1) = 2

Answer: The original number is 2.

Suppose the number is a, and the decimal point is moved two places to the right, which is a 100-fold expansion.

This gives the equation 100a-a=198;a=

Move the decimal point two places to the right to become 200; 200-2=198 The original number is.

The decimal point of a number is shifted two places to the right, representing a 100-fold expansion of the original number. If the original number is set to x, the new number is 100x. Because the decimal point of a number is 198 greater than the original number after moving two decimal places to the right, then 100x x 198.

i.e. x 198 (100 1) 198 99 2. Therefore, the original number is 2.

Summary. Hello dear If the decimal point is moved to the right by one place, the original number will be expanded by 10 times, and if the decimal point is moved to the left, the original number will be reduced by 100 times; [Eat whales] [eat whales].

After moving the decimal point of a number to the right by two places, the resulting number is 198 greater than the original number, what is the original number?

You know that 198 100 -1) =2Answer: The original number is 2 charters. Analyze the decimal of a number, the point is moved to the right by two places, this number will be expanded to 100 times the original, and the original number will be regarded as 1 part, and the expanded number will be such 100 parts, 99 more than the original number, so the original number = 198 100-1).

Hello dear If the decimal point is moved to the right by one place, the original number will be expanded by 10 times, and if the decimal point is moved to the left, the original number will be reduced by 100 times; [Eat whales] [eat whales].

If the original number is , you can get a closed form like this:

The decimal point can be expressed as follows: 100 is greater than the original 198, and you get: 100- =198, so the original number is: 2

Move two places to the right, which is multiplied by 100

The original number of the skin servant is x, and the side plan of one yuan is one time: burning faction.

100x-x=198

99x=198

x=198÷99

x=2 Answer: The original number is 2

Hope, thank you.

Answer: Let the original number be x.

100x-x=198

99x=198

x=2 is 2.
