To find out how much baking soda Lisa should add to 9 lbs. of flour, we can set up a ratio based on the given information.
The ratio of baking soda to flour is 2 tsp to 6 lbs.
We can set up a proportion:
2 tsp / 6 lbs = x tsp / 9 lbs
To solve for x, we can cross multiply:
(2 tsp) * (9 lbs) = (6 lbs) * (x tsp)
18 tsp = 6 lbs * x
Dividing both sides by 6 lbs, we get:
18 tsp / 6 lbs = x
Simplifying:
3 tsp = x
Therefore, Lisa should add 3 tsp of baking soda to 9 lbs of flour.
To solve this problem, we need to determine the ratio of baking soda to flour. In this case, Lisa adds 2 teaspoons of baking soda to 6 pounds of flour.
To find out how much baking soda should be added to 9 pounds of flour, we need to set up a proportion.
Let's set up the proportion using the ratio of baking soda to flour:
2 tsp / 6 lbs = x tsp / 9 lbs
Cross multiplying, we get:
2 tsp * 9 lbs = 6 lbs * x tsp
18 tsp = 6x tsp
Now, we can solve for x by dividing both sides of the equation by 6:
18 tsp / 6 = x tsp
3 tsp = x tsp
So, Lisa should add 3 teaspoons of baking soda to 9 pounds of flour. Therefore, the correct answer is 3 tsp.
