If Lisa adds 2 tsp of baking soda to 6 lbs. of flour, the ratio of baking soda to flour is 2 tsp / 6 lbs.
To find out how much baking soda she should add to 9 lbs. of flour, we can set up a proportion:
2 tsp / 6 lbs. = x tsp / 9 lbs.
Cross multiplying, we get:
6 lbs. * x tsp = 2 tsp * 9 lbs.
6x = 18
Dividing both sides by 6, we find:
x = 3 tsp.
So, Lisa should add 3 tsp of baking soda to 9 lbs. of flour. Answer: \boxed{3}.
To find out how much baking soda Lisa should add to 9 lbs. of flour, we need to set up a proportion based on the ratio of baking soda to flour.
The ratio of baking soda to flour is 2 tsp:6 lbs.
Let's set up the 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 = 6 lbs * x tsp
To isolate x, divide both sides of the equation by 6 lbs:
18 tsp / 6 lbs = x tsp
Simplifying the expression:
3 tsp = x tsp
Therefore, Lisa should add 3 tsp of baking soda to 9 lbs. of flour.
To find out how much baking soda Lisa should add to 9 lbs. of flour, we can use the concept of ratios.
First, let's determine the ratio of baking soda to flour in the given situation. We know that Lisa adds 2 tsp of baking soda to 6 lbs. of flour. So the ratio of baking soda to flour can be written as:
2 tsp / 6 lbs.
Next, we can use this ratio to find out the amount of baking soda needed for 9 lbs. of flour.
We can set up a proportion as follows:
2 tsp / 6 lbs. = x tsp / 9 lbs.
To solve this proportion, we can cross-multiply and then divide:
2 tsp * 9 lbs. = 6 lbs. * x tsp
18 tsp = 6x tsp
Now, we can solve for x (the amount of baking soda needed for 9 lbs. of flour):
x = (18 tsp) / 6
x = 3 tsp
Therefore, Lisa should add 3 tsp of baking soda to 9 lbs. of flour.
