Lisa has two teaspoon baking soda to 6 lb of flour how much baking soda should she add to 9 lb of flour a 2017 B 3 tsp 9 teaspoons D 18 tsp

Answer 1

To determine how much baking soda Lisa should add to 9 lb of flour, we first need to establish the ratio of baking soda to flour.

Lisa's original ratio is:

• 2 teaspoons of baking soda for 6 lb of flour.

We can simplify this ratio to find out how much baking soda is needed per pound of flour:

• \( \frac{2 \text{ tsp}}{6 \text{ lb}} = \frac{1 \text{ tsp}}{3 \text{ lb}} \)

Now, we need to find out how much baking soda is needed for 9 lb of flour. If 1 teaspoon is required for every 3 lb, then for 9 lb, the calculation is:

• \( \text{Baking Soda} = 9 \text{ lb} \times \frac{1 \text{ tsp}}{3 \text{ lb}} = 3 \text{ tsp} \)

Therefore, Lisa should add 3 teaspoons of baking soda for 9 lb of flour.

The correct answer is B: 3 tsp.
