−3

Answer 1

To determine which numbers could be used to specify how many cups of flour should be used in a bread recipe, we need to consider that the number of cups of flour must be a non-negative rational number. This means it should be zero or a positive number.

Now let's evaluate the options given:

1. **Square root of 3** - This is approximately 1.732, which is positive and could be a valid measurement.

2. **47** - This is a positive whole number, so it is valid.

3. **4/7** (Start Fraction 4 over 7 End Fraction) - This is a positive fraction, which means it is valid.

4. **234** - This is also a positive whole number, so it is valid.

5. **2 3/4** (2 Start Fraction 3 over 4 End Fraction) - This is a positive mixed number, which can also be converted to a decimal (2.75) and is valid.

6. **−3** - This is negative, which cannot be used for a measurement of flour. Therefore it is invalid.

All the mentioned values except for -3 are valid options. Therefore, the valid responses for how many cups of flour could be used in a bread recipe are:

- Square root of 3
- 47
- 4/7
- 234
- 2 3/4

Choose any of these numbers except for -3.
