   Full step-by-step solution

   Step 1: Identify the number of shells in each group. The first group has 4 shells. The second group has 2 shells. The third group has 1 shell. Step 2: To find the total number of shells, we need to add the shells from all three groups together. So we write the addition expression: 4 + 2 + 1 Step 3: First, add the first two numbers: 4 + 2 = 6 Step 4: Now add the result to the third number: 6 + 1 = 7 Step 5: Conclusion. Lily has 7 shells in total.

2. Liam is building a number using base-ten blocks. He uses 7 hundreds flats, 3 tens rods, and 9 ones units. What number is shown by Liam's blocks? Answer: 739 Solution: Count the hundreds. Liam has 7 hundreds flats. 7 hundreds = 700.
   Full step-by-step solution

   Step 1: Count the hundreds. Liam has 7 hundreds flats. 7 hundreds = 700. Step 2: Count the tens. Liam has 3 tens rods. 3 tens = 30. Step 3: Count the ones. Liam has 9 ones units. 9 ones = 9. Step 4: Add the values together: 700 + 30 + 9 = 739. The number shown by Liam's blocks is 739.
