Answer 1

To find 80% of 630, Allison should use a table that allows her to break down the percentage calculation into manageable parts.

Looking at the options:

1. The first option breaks down into five 20% sections, which could be combined to find 80% (20% + 20% + 20% + 20% = 80%).
2. The second option has four 25% sections which sums to 100%, but does not directly relate to 80%.
3. The third option has three 40% sections which sums to 120%, exceeding 100%.
4. The fourth option uses 8% sections, which also allows for smaller increments but does not align neatly to 80%.

The best choice is Option 1, as it allows Allison to calculate 80% by summing four instances of 20%.

So, the answer is Option 1.
