Answer 1

To find the correct relationship between cups and tablespoons, we need to remember that there are 16 tablespoons in 1 cup. This means that to convert cups to tablespoons, we multiply the number of cups by 16.

Now, let's calculate the number of tablespoons for each entry in the first column of the first option, which are 1, 2, 4, and 8 cups:

- 1 cup = 1 * 16 = 16 tablespoons
- 2 cups = 2 * 16 = 32 tablespoons
- 4 cups = 4 * 16 = 64 tablespoons
- 8 cups = 8 * 16 = 128 tablespoons

The resulting table would be:

| Cups | Tablespoons |
|------|-------------|
| 1 | 16 |
| 2 | 32 |
| 4 | 64 |
| 8 | 128 |

Now, looking at the choices provided:

1. **First choice:**
- Cups: 1, 2, 4, 8
- Tablespoons: 16, 32, 64, 128 (This matches)

2. **Second choice:**
- Cups: 16, 32, 64, 128
- Tablespoons: 1, 2, 4, 8 (This does not match)

3. **Third choice:**
- Cups: 32, 48, 80, 144
- Tablespoons: 16, 32, 64, 128 (This does not match)

4. **Fourth choice:**
- Cups: 16, 32, 64, 128
- Tablespoons: 32, 48, 80, 144 (This does not match)

The **first choice** is the correct table that relates the number of cups to the number of tablespoons.
