Answer 1

Sure! Let's fill in the blanks step by step.

1. **How many groups?**
**42**

2. **Write the dividend in expanded form.**
**127 = 100 + 20 + 7** (the correct expanded form)

3. **Regroup the hundreds piece into 10 tens.**
**We have 10 tens (which is 100) and now we can combine it with the 20 to have 30 tens.**

4. **The quotient is the size of the groups. There is 1 left over:**
**42 R1**

5. **Check the answer. Multiply the quotient by the divisor and add the remainder.**
**42 x 3 = 126**
**Add the remainder (1): 126 + 1 = 127**

6. **Our answer is confirmed.**

So the filled-in blanks look like this:

- How many groups? **42**
- Write the dividend in expanded form:
**127 = 100 + 20 + 7**
- Regroup the hundreds piece into 10 tens:
**(100 becomes 10 tens)**
- The quotient is the size of the groups. There is 1 left over:
**42 R1**
- Check the answer. Multiply the quotient by the divisor and add the remainder:
**42 x 3 = 126 + 1 = 127**
- Our answer is confirmed.
