When specifying how many cups of flour should be used in a bread recipe, it's best to use a number that makes practical sense in a cooking context, typically a non-negative whole number or a decimal/fraction that represents a reasonable amount of flour.
Let's evaluate the options:
A. \( \frac{4}{7} \) - This is a fraction that represents a part of a cup. It can be used in a recipe but is not a whole number. B. \( 2 \frac{3}{4} \) - This is a mixed number that represents 2.75 cups, which is a reasonable amount for a recipe. C. \( 3 \) - This is a whole number and a very reasonable amount for cups of flour in a recipe. D. Square root of 3 - This is an irrational number (approximately 1.732), which is not a common or easily measurable quantity for a recipe.
The best candidates to specify how many cups of flour should be used in a bread recipe are:
- B. \( 2 \frac{3}{4} \)
- C. \( 3 \)
Therefore, options B and C could suitably specify the amount of flour.
