Let’s solve each sentence step by step, using the concept of
place value — specifically,
tens and ones.
---
🔹 1. `19` has ___ ten and ___ ones
- The number
19 is made up of:
-
1 in the tens place →
1 ten
-
9 in the ones place →
9 ones
✔ Answer:
19 has 1 ten and 9 ones
---
🔹 2. `67` has ___ tens and ___ ones
- The number
67:
-
6 in the tens place →
6 tens
-
7 in the ones place →
7 ones
✔ Answer:
67 has 6 tens and 7 ones
---
🔹 3. ___ has 3 tens and 4 ones
- 3 tens = 3 × 10 =
30
- 4 ones = 4 × 1 =
4
- Total = 30 + 4 =
34
✔ Answer:
34 has 3 tens and 4 ones
---
🔹 4. ___ has 7 tens and 0 ones
- 7 tens = 7 × 10 =
70
- 0 ones = 0
- Total = 70 + 0 =
70
✔ Answer:
70 has 7 tens and 0 ones
---
🔹 5. ___ has 0 tens and 25 ones
- This one is a bit tricky! Normally, we don’t write numbers with more than 9 ones — but mathematically, it’s valid.
- 0 tens = 0
- 25 ones = 25
- So the total number is
25
> 💡 Note: Even though 25 is usually written as “2 tens and 5 ones”, the problem says “0 tens and 25 ones” — so we accept that representation for this exercise.
✔ Answer:
25 has 0 tens and 25 ones

##
✔ Final Answers:
1.
19 has
1 ten and
9 ones
2.
67 has
6 tens and
7 ones
3.
34 has 3 tens and 4 ones
4.
70 has 7 tens and 0 ones
5.
25 has 0 tens and 25 ones

📌
Key Concept: In a two-digit number, the
left digit tells you how many
tens, and the
right digit tells you how many
ones. But you can also express numbers in non-standard ways (like 0 tens and 25 ones) to reinforce understanding of place value.
