To determine how much baking soda Lisa should add to 9 lbs. of flour, we need to find the ratio of baking soda to flour in the first scenario.
The given ratio is 2 tsp of baking soda to 6 lbs. of flour.
We can set up a proportion to find the unknown amount of baking soda:
2 tsp / 6 lbs. = x tsp / 9 lbs.
To solve this proportion, we can cross-multiply:
6 * x tsp = 2 * 9 lbs.
6x = 18
Now, we can solve for x by dividing both sides of the equation by 6:
x = 18 / 6
x = 3 tsp
Therefore, Lisa should add 3 tsp of baking soda to 9 lbs. of flour. So the correct response is:
3 tsp
To find out how much baking soda Lisa should add to 9 lbs. of flour, we can set up a proportion based on the ratio of baking soda to flour in the first scenario:
2 tsp baking soda / 6 lbs. flour = x tsp baking soda / 9 lbs. flour
Now we can cross-multiply and solve for x:
(2 tsp)(9 lbs.) = (6 lbs.)(x tsp)
18 tsp = 6x tsp
Divide both sides of the equation by 6:
18 tsp / 6 = 6x tsp / 6
3 tsp = x tsp
Therefore, Lisa should add 3 tsp of baking soda to 9 lbs. of flour.
