Answer:
We can not tell which one is greater
Step-by-step explanation:
* Lets explain how to solve the number
- A digit is a single whole number from 0 to 9 in a number start from
10 or larger
- Place value can be defined as the value a digit in a number according
to its position in the number
- The digits of the number arranged from right to left
* <u><em>The greatest number who has the greatest leftmost digits when</em></u>
<em> </em><u><em>they have the same number of digits</em></u>
- Ex : 147 ⇒ 100 + 40 + 7
621 ⇒ 600 + 60 + 1
- The greatest number is 621 because the leftmost digit in the
second number greater than the leftmost digit in the first number
* <u><em>If the numbers do not have the same number of digits we can't say</em></u>
<em> </em><u><em>which number is greater</em></u>
- Ex: 86 ⇒ 80 + 6
324 ⇒ 300 + 20 + 3
- The leftmost digit in the first number is tens and the leftmost digit
in the second number is hundreds, of course hundreds are greater
than tens
- Then the number with leftmost digit 3 is greater than the number
with leftmost digit 8
* It depends on the two numbers have the same number of digits or
different number of digits
∴ We can not decide which one is greater
∴ <u><em>We can not tell which one is greater</em></u>
