Lisa adds 2 tsp baking soda to 6 Ibs. of flour. How much baking soda should she add to 9 Ibs. of flour?

Answer 1

To determine the amount of baking soda to add to 9 Ibs. of flour, we can set up a proportion using the relationship between the amount of baking soda and the amount of flour.

Let x represent the amount of baking soda to add to 9 Ibs. of flour.

Since there is 2 tsp. of baking soda for every 6 Ibs. of flour, we can set up the proportion:

2 tsp / 6 Ibs = x tsp / 9 Ibs.

Cross-multiplying, we have:

2 tsp * 9 Ibs = 6 Ibs * x tsp.

18 tsp = 6 Ibs * x tsp.

Dividing both sides by 6 Ibs, we get:

18 tsp / 6 Ibs = x tsp.

Simplifying, we have:

3 tsp = x tsp.

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