Digit Comparison Challenge: Hundreds Less Than Units Position

Q: How do I remember which digit is in the hundreds place?

Count from the right side! In any 3-digit number like 637, the rightmost digit (7) is units, middle digit (3) is tens, and leftmost digit (6) is hundreds.

Q: What if the hundreds and units digits are equal?

If they're equal, like in 909 where both are 9, then the hundreds digit is not less than the units digit. We need the hundreds digit to be smaller.

Q: Can I use 2-digit numbers for this problem?

No! A 2-digit number like 45 has no hundreds digit at all. You need at least a 3-digit number to have a hundreds place to compare.

Q: Why isn't 241 correct if 2 and 1 are different?

Because $ 2 > 1 $, not \( 2 ! We need the hundreds digit to be less than the units digit, which means smaller.

Q: How can I quickly check all the answer choices?

Understand the problem

Choose a number whose hundreds digit is less than its units digit.

Step-by-step solution

To solve this problem, we need to follow these steps:

Step 1: List out the given choices.
Step 2: Examine each number's hundreds and units digits.
Step 3: Determine which number has a hundreds digit less than its units digit.

Let’s perform the analysis:

Step 1: Examine each choice.

Choice 1: $241$ – Hundreds digit: $2$ , Units digit: $1$
Choice 2: $637$ – Hundreds digit: $6$ , Units digit: $7$
Choice 3: $895$ – Hundreds digit: $8$ , Units digit: $5$
Choice 4: $909$ – Hundreds digit: $9$ , Units digit: $9$

Step 2: Compare hundreds and units digits.

For $241$ , $2 \not< 1$
For $637$ , $6 < 7$
For $895$ , $8 \not< 5$
For $909$ , $9 \not< 9$

Step 3: From our analysis, the correct answer is $637$ as its hundreds digit $6$ is less than its units digit $7$ .

Therefore, the solution to the problem is $637$ .

Final Answer

$637$

Key Points to Remember

Essential concepts to master this topic

Place Value Rule: Hundreds digit is third from right, units is rightmost
Technique: Compare 637: hundreds digit 6 < units digit 7

Common Mistakes

Avoid these frequent errors

Confusing hundreds and tens positions
Don't identify the middle digit as hundreds in a 3-digit number = wrong position analysis! The middle digit is actually the tens place. Always count from right: units (1st), tens (2nd), hundreds (3rd).
