Answer :

Let's determine which option has the same value as 12 tens.

First, we need to understand what "12 tens" means. It's another way of expressing how many tens are in the number 120 (since 12 tens equals 120).

Now we want to compare this with the given options:

1. O2 hundreds 2 tens

- 2 hundreds = 200
- 2 tens = 20
- Total = 220

2. OI hundred 2 tens

- 1 hundred = 100
- 2 tens = 20
- Total = 120

3. O 2 tens I one

- 2 tens = 20
- 1 one = 1
- Total = 21

4. OI ten 2 ones

- 1 ten = 10
- 2 ones = 2
- Total = 12

By comparing the total values, we see that the option "OI hundred 2 tens" matches the value of 12 tens, which is 120.

Thus, the correct answer is:

OI hundred 2 tens
