Let’s go step by step to solve this.
We are breaking each number into “tens” and “ones”.
That means we look at how many groups of 10 are in the number (that’s the tens), and what’s left over (that’s the ones).
---
First number: 12
- How many tens? → 1 ten (because 10 fits once)
- What’s left? → 2 ones
→ So:
1 ten + 2 ones
Second number: 17
- How many tens? → 1 ten
- Leftover? → 7 ones
→ So:
1 ten + 7 ones
Third number: 5
- How many tens? → 0 tens (since 5 is less than 10)
- Leftover? → 5 ones
→ So:
0 tens + 5 ones
Fourth number: 11
- How many tens? → 1 ten
- Leftover? → 1 one
→ So:
1 ten + 1 one
Fifth number: 20
- How many tens? → 2 tens (because 10 + 10 = 20)
- Leftover? → 0 ones
→ So:
2 tens + 0 ones
Sixth number: 8
- How many tens? → 0 tens (less than 10)
- Leftover? → 8 ones
→ So:
0 tens + 8 ones
✔ All checked — these make sense!
Final Answer:
12 = 1 tens + 2 ones
17 = 1 tens + 7 ones
5 = 0 tens + 5 ones
11 = 1 tens + 1 one
20 = 2 tens + 0 ones
8 = 0 tens + 8 ones
