To find the amount of baking soda that Lisa should add to 9 lbs. of flour, we can use a proportion.
If 2 tsp of baking soda is added to 6 lbs. of flour, then the proportion is:
2 tsp / 6 lbs. = x tsp / 9 lbs.
Cross multiplying, we get:
2 * 9 = 6 * x
18 = 6x
Dividing both sides by 6, we find:
x = 3
So, Lisa should add 3 tsp of baking soda to 9 lbs. of flour.
Therefore, the correct answer is 3 tsp.
To find out how much baking soda Lisa should add to 9 lbs. of flour, we can set up a ratio using the given information.
The ratio of baking soda to flour is 2 tsp to 6 lbs.
To find the amount of baking soda for 9 lbs. of flour, we can set up the following proportion:
2 tsp / 6 lbs. = X tsp / 9 lbs.
Cross-multiplying, we get:
6 lbs. * X tsp = 2 tsp * 9 lbs.
Simplifying:
6X = 18
Dividing both sides by 6:
X = 3
Therefore, Lisa should add 3 tsp of baking soda to 9 lbs. of flour.
So the correct answer is 3 tsp.
To find out how much baking soda Lisa should add to 9 lbs. of flour, we can use a proportion to set up the relationship between the amount of baking soda and the amount of flour.
We know that Lisa added 2 tsp of baking soda to 6 lbs. of flour. Let's represent this as a ratio:
2 tsp of baking soda / 6 lbs. of flour
Now, we can set up a proportion using this ratio to find the amount of baking soda for 9 lbs. of flour:
x tsp of baking soda / 9 lbs. of flour
To solve for x, we can cross-multiply and then divide:
2 tsp * 9 lbs. = x tsp * 6 lbs.
18 tsp = 6x
To isolate x, divide both sides of the equation by 6:
18 tsp / 6 = x
x = 3 tsp
Therefore, Lisa should add 3 tsp of baking soda to 9 lbs. of flour.
