Question

Add: 43 + 138
34 + 138 = 181

3 ones plus 8 ones is equal to _ ones.
11 ones in the same as 1 _ and 1 one. Trade in for a tens piece.
We have 1 ten plus 4 tens plus 3 tens. That's _ tens.
We end up with 1 hundred, 8 tens, and the 1 one, or _.
Fill in all the blanks

Answer 1

Let's break it down step by step to fill in the blanks.

1. **43 + 138:** First, let's calculate the total.
- \( 3 + 8 = 11 \): This means that 3 ones plus 8 ones equals **11 ones**.
- Trade in: 11 ones is the same as 1 **ten** and 1 one, so we would trade in for a tens piece.

2. Now, we count the tens:
- You have 1 ten from the trading, plus 4 tens from 43 (which is 40) plus 3 tens from 138 (which is 30).
- Thus, \( 1 + 4 + 3 = 8 \): So, we have **8 tens**.

3. Finally, we look at the hundreds, tens, and ones:
- From the addition, we end up with 1 hundred, 8 tens, and 1 one, which means the final answer is **181**.

So the filled in blanks are:
- 11 ones
- 10
- 8 tens
- 181
