To determine which of the given options could specify how many cups of flour should be used in a bread recipe, we should consider whether the number is a positive quantity and whether it makes sense in the context of measuring ingredients.
-
4 over 7: This is a positive fraction (approximately 0.57). This could represent a valid amount of flour to use.
-
2 and 3 over 4: This is a mixed number, which is positive (equal to 2.75). This is also a valid amount of flour to use.
-
−3: This is a negative number. You cannot use a negative amount of flour, so this option is not valid.
-
square root of 3: The square root of 3 is approximately 1.73, which is a positive quantity and could represent a valid amount of flour to use.
Based on this analysis, the options that could be used to specify how many cups of flour should be used in a bread recipe are:
- 4 over 7
- 2 and 3 over 4
- square root of 3
Therefore, the valid options are 4 over 7, 2 and 3 over 4, and square root of 3.
