What is the value of the digit 5 in the number 523?
A5
B50
C500
D5,000
The digit 5 is in the hundreds place, so its value is 5 × 100 = 500. The face value of 5 is just 5, but place value depends on position. Students often confuse the digit itself (5) with its positional value (500).
Question 2 True / False
The number 307 has 3 hundreds, 7 tens, and 0 ones.
TTrue
FFalse
Answer: False
307 has 3 hundreds, 0 tens, and 7 ones — written as 300 + 0 + 7. The zero in the middle is a placeholder for the tens place, not the ones place. Confusing the positions of tens and ones is one of the most common errors with three-digit numbers.
Question 3 Short Answer
How many tens make one hundred?
Think about your answer, then reveal below.
Model answer: 10 tens make one hundred.
This is the core place-value pattern: each place is worth ten times the place to its right. Just as 10 ones make a ten, 10 tens make a hundred. Understanding this grouping pattern is what makes our base-ten number system work.
