Place value is compared to find the least and greatest numbers.

Question 2.

Answer:

Explanation:

When we compare numbers, check if both the numbers are having the same number of digits. If a number has more digits, then it is greater than the other number.

when two numbers are having the same number of digits,

we need to check the digit at the leftmost place, whichever is greater.

But if the left-most digit of both the numbers is the same,

then we need to check with the second left-most digit or so on.

Thus, in this way, we can find the greater or smaller number.

Question 3.

Answer:

Explanation:

When we compare numbers, check if both the numbers are having the same number of digits. If a number has more digits, then it is greater than the other number.

when two numbers are having the same number of digits,

we need to check the digit at the leftmost place, whichever is greater.

But if the left-most digit of both the numbers is the same,

then we need to check with the second left-most digit or so on.

Thus, in this way, we can find the greater or smaller number.
