Answer with step-by-step explanation:

The question does not seem complete, but I'll try to make some explanations.

When you want to round a number, there are some rules.

1. If the number you are rounding is followed by 5, 6, 7, 8, 9, then round the number up, that is add 1 to it.

2. If the number you are rounding is followed by 0, 1, 2, 3, 4, then round the number down, that is add 0.

Now if given a number and you are asked to round to the nearest 100, 1 000, 10 000 and so on, then for nearest 100, count 2 numbers from the back. Whatever number you stop at, that is the number you are to round. For 1000 count 3, for 10 000 count 4 and so on.

Since Kiara is having the same value after rounding, it means she picked a number that has zeros after the 10 000th value

Let's assume she picked: 70 000

Rounding that number to nearest 100, 1000 and 10000 gives the same number which is

70 000.
