In a bread recipe, the amount of flour used is typically expressed as a non-negative quantity, often in whole numbers or fractions. Let's analyze the choices given:
- 234 - This is a positive whole number and could represent cups of flour.
- 2 Start Fraction 3 over 4 End Fraction - This represents 2.75 cups and is also a valid positive quantity.
- 47 - This is another positive whole number and could also represent cups of flour.
- Start Fraction 4 over 7 End Fraction - This is a positive fraction (approximately 0.57), which can also represent a valid amount of flour.
- −3 negative 3 - This is a negative number and cannot represent a quantity of flour.
- square root of something - The square root value would depend on what it is rooted from. If it were a positive quantity, the square root would also be positive; if it's negative, it could be invalid.
From this assessment, the numbers that could specify how many cups of flour should be used in a bread recipe are:
- 234
- 2 Start Fraction 3 over 4 End Fraction
- 47
- Start Fraction 4 over 7 End Fraction
Negative values and quantities that are not certain (like the square root without context) would not be valid for this scenario.
