Lisa adds 2 tsp baking soda to 6 lbs. of flour. How much baking soda should she add to 9 lbs. of flour?(1 point) Responses 27 tsp 27 tsp 3 tsp 3 tsp 1
The correct answer is 3 tsp.
To calculate the amount of 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) = (6 lbs. flour) * (x tsp baking soda)
18 tsp baking soda = 6 lbs. flour * x tsp baking soda
Now, let's solve for x by dividing both sides of the equation by 6 lbs. flour:
18 tsp baking soda / 6 lbs. flour = x tsp baking soda
3 tsp baking soda = x
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 set up a proportion based on the ratio of baking soda to flour.
We know that Lisa adds 2 tsp of baking soda to 6 lbs. of flour. Let's denote the amount of baking soda she should add to 9 lbs. of flour as x.
The proportion can be set up as:
2 tsp / 6 lbs. = x tsp / 9 lbs.
To find x, we can cross-multiply and solve for x:
2 tsp * 9 lbs. = 6 lbs. * x tsp
18 tsp = 6x tsp
Now, let's isolate x by dividing 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.
