Question

which of the following numbers could be used to specify how many cups of flowers should be used in a bread recipe?

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

Answer 1

In a recipe, the number of cups of an ingredient should be a positive rational number, typically expressed in terms of whole numbers or fractions.

Let's evaluate the options:

1. **4/7** - This is a positive fraction and could be used to represent a portion of a cup, so it is acceptable.
2. **Square root of 3** - This is an irrational number and not a standard way to measure ingredients, so it wouldn't be suitable.
3. **2 3/4** - This is a positive mixed number (2 + 3/4) and is acceptable for measuring ingredients.
4. **-3** - This is a negative number and cannot represent a quantity of cups in a recipe, so it is not suitable.

Therefore, the numbers that could be used to specify how many cups of flowers should be used in a bread recipe are **4/7** and **2 3/4**.
