When a number is expanded to 100 times its size, it is 100 98 more than the original number, and the

Let the original number be x; After expanding by 100 times, it is x(1+100), which is larger than the original number; Therefore x(1+100)=x+ ==> x=, i.e., x=. Answer: The original number is.

Check: After expanding by 100 times, this is larger than the original number, so it is in line with the title).

Original Number = Ask how it was obtained When a number is expanded to 100 times its size, it is 100-1 times more than the original number.

Let's use equations to compare your teaching:

Solution: Let the original number be x, then expand to 100 times it to 100x100x-x=

99x=x=A: The original number is.

The original number = the original number is doubled, so subtract 1 from 100.

The above method is correct.

There's an easier way to do it.

A hundred times more than the original number, that is, 99 times the original number, divided by 99=, is the original number.

Let the original number be x, then 100x-x=. So 99x=. So x=.

The original number is.

Kid, you're really awesome, you actually came here to find the answer I'm dizzy.

Hey, now the teachers are crazy, and we have to find 、、、 these topics here

I'm a primary school student, how can I solve it without equations?

The current number is 100 times the original number of Kitsa, and if you look at the current number in front of the shirt as 100 parts, the original number is 1 part.

The original number of the slapping eggplant.

Solution: (1) "After a number is expanded to 100 times its size", it is 99 times more than the original; In other words, it is 99 times the original number.

2) Answer: A number expands to 100 times its size and is more than the original number, and the original number is.

Hope it helps!

Think of this number as 1 part, expanding 100 times is 100 parts, and the difference between them is, then it is 100 parts - 1 part = 99 parts is, find the original number, that is, find how much 1 part is, so use .

<> please see the specific process of solving the problem, I hope it will be helpful to you.

Normal method:

Equation method: Solution: Let the original number be x, then expand to 100 times it is 100x100x-x=

99x=x=A: The original number is.

1 When all a number is expanded to 100 times his number, it is more than the original number.

More than the original number: 100 1 99 times, the original number =, Answer: The original number is,

Solution: Let the original number be x

100x-x=

99x=x=The original number is.

Original = Hope this helps.

Thank you for adopting.

is 99 times the original number, so, the original number is:
