To find out how much baking soda Lisa should add to 9 lbs. of flour, we can set up a proportion:
2 tsp baking soda / 6 lbs. flour = x tsp baking soda / 9 lbs. flour
Cross-multiplying, we get:
2 tsp baking soda * 9 lbs. flour = x tsp baking soda * 6 lbs. flour
18 tsp baking soda = 6x tsp baking soda
Dividing both sides by 6, we have:
3 tsp baking soda = x tsp baking soda
Therefore, Lisa should add 3 tsp of baking soda to 9 lbs. of flour.
