To determine how much flour Maria will need for a batch of 48 cookies using a double number line, we first need to know the amount of flour required for a known quantity of cookies.
Assuming we know that a certain amount of flour is needed for a specific number of cookies (for example, 2 cups of flour for 24 cookies), we can set up the proportion.
Let's say:
- 2 cups of flour are needed for 24 cookies.
To find out how much flour is needed for 48 cookies, we can use a ratio:
-
Set up the ratio: \[ \frac{2 \text{ cups}}{24 \text{ cookies}} = \frac{x \text{ cups}}{48 \text{ cookies}} \]
-
Cross-multiply: \[ 2 \times 48 = 24 \times x \] \[ 96 = 24x \]
-
Solve for x: \[ x = \frac{96}{24} = 4 \]
Therefore, Maria will need 4 cups of flour to make a batch of 48 cookies.
