Answer:
Same digits till the ones digits
Same digits till tens digits
Explanation:
* Lets explain how to solve the problem
- The numbers on the left are 5,278 and 5,272
- When we compare any to numbers with the same number of digits
we must start from the leftmost digit and go to the right
∵ The two numbers have 4 digits ⇒ thousands - hundreds - tens - one
∵ The leftmost digits in the 2 numbers (thousands) are equal
∵ The hundreds digits of the 2 number are equal
∵ The tens digits of the 2 number are equal
∴ We must to look at the ones digits to compare between them
∴ We need to look at the ones digits
- The numbers on the right are 5398 and 5353
∵ The two numbers have the thousands digits
∵ The two numbers have the same hundred digits
∵ The two numbers not having the same tens digits
∴ We compare between them using the tens digits not the
ones digits
∴ We do not need to compare the ones digits
