Divide: 127 and 3
How many groups? _
Write the dividend in expanded form.
127 divided by 3
127 = 100 + _ + 7
Regroup the hundreds piece into 10 tens.
The quotient is the size of the groups. There is 1 left over:

Our answer is confirmed.

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.
