ones that represent the collection.

____ ones
____ groups of
ten in ____
decompose this number in two different ways.
____ hundreds
____ tens
____ ones
____ hundreds
____ tens
____ ones

Explanation:

Step1: Count full hundreds (100 seeds each)

First 4 rows: $4 \times 10 = 40$ full packs (10 seeds each) = $40 \times 10 = 400$ seeds, so 4 hundreds.

Step2: Count full tens (10 seeds each)

Partial 5th row: 2 full packs = $2 \times 10 = 20$ seeds, so 2 tens.

Step3: Count remaining ones

Last partial pack: 6 seeds, so 6 ones.

Step4: Total number calculation

Total = $400 + 20 + 6 = 426$

Step5: Verify groups of ten

$\frac{426}{10} = 42$ full groups of ten (remainder 6 ones)

Step6: Decompose (Way 1)

Convert 1 hundred to 10 tens: $3$ hundreds + $(10+2)$ tens + $6$ ones = 3 hundreds, 12 tens, 6 ones

Step7: Decompose (Way 2)

Convert 2 hundreds to 20 tens: $2$ hundreds + $(20+2)$ tens + $6$ ones = 2 hundreds, 22 tens, 6 ones

Answer:

First Section:

4 Hundreds
2 Tens
6 Ones
42 groups of ten in 426

Decomposition (Way 1):

3 Hundreds
12 Tens
6 Ones

Decomposition (Way 2):

2 Hundreds
22 Tens
6 Ones
