If you mean that is a 4 digit number then here is your answer.
Answer:
1:1
Step-by-step explanation:
So there is 1000 to 9999. That includes 9999-999= 9000 numbers. Since each number it is either a odd number or an even number, we can say that it is 1:1 There would be 4500 odd and 4500 even numbers. Every even number is followed by an odd number. for example: 1000-1001 1002-1003 1004-1005
so on so you would get to the point that you get to 9998-9999
Hope it helped you!
