Answer 1

[AI-generated answer — Step-by-Step Bot]

To find the proportion of baking soda to flour, we can set up a ratio based on the given information:

2 tsp baking soda / 6 lbs flour = x tsp baking soda / 9 lbs flour

To solve for x, we can cross-multiply and then divide:

2 tsp baking soda * 9 lbs flour = 6 lbs flour * x tsp baking soda

18 tsp baking soda = 6x

To isolate x, divide both sides of the equation by 6:

18 tsp baking soda / 6 = x

Simplifying the equation, we get:

3 tsp baking soda = x

Therefore, Lisa should add 3 tsp of baking soda to 9 lbs of flour.

The correct answer is B. 3 tsp.

Answer 2

[AI-generated answer — Bot GPT 3.5]

To solve this problem, we can use a ratio.

The ratio of baking soda to flour is 2 tsp:6 lbs.

To find the amount of baking soda for 9 lbs of flour, we can set up a proportion:

2 tsp/6 lbs = x tsp/9 lbs

Cross multiplying, we get:

6x tsp = 2 tsp * 9 lbs

Simplifying, we have:

6x tsp = 18 tsp * lbs

Dividing both sides by 6 tsp, we find:

x = 18 tsp

Therefore, Lisa should add 18 tsp of baking soda to 9 lbs of flour, which is option A.

Answer 3

To solve this problem, we need to determine the ratio of baking soda to flour.

In the given scenario, Lisa adds 2 teaspoons of baking soda to 6 pounds of flour. So, we can write the ratio as 2 tsp: 6 lbs.

To find out how much baking soda Lisa should add to 9 pounds of flour, we need to calculate the equivalent ratio.

Since the ratio of baking soda to flour remains constant, we can set up the following proportion:

2 tsp / 6 lbs = x tsp / 9 lbs

Now, we can cross-multiply and solve for x:

(2 tsp) * (9 lbs) = (6 lbs) * (x tsp)

18 tsp lbs = 6x tsp

Dividing both sides of the equation by 6:

(18 tsp lbs) / 6 = (6x tsp) / 6

3 tsp = x

Therefore, Lisa should add 3 teaspoons of baking soda to 9 pounds of flour.

So, the correct answer is B. 3 tsp.
