Lisa adds 2 tsp baking soda to 6 lbs. of flour. How much baking soda should she add to 9 lbs. of flour?
Options:
3 tsp
18 tsp
27 tsp
9 tsp
To determine the amount of baking soda Lisa should add to 9 lbs. of flour, we can use the ratio of baking soda to flour.
The ratio of baking soda to flour is 2 tsp / 6 lbs. We can simplify this ratio by dividing both the numerator and denominator by 2:
1 tsp / 3 lbs.
Now, we can set up a proportion to find the amount of baking soda Lisa should add to 9 lbs. of flour:
1 tsp / 3 lbs. = x tsp / 9 lbs.
To solve for x, we can cross multiply:
1 * 9 = 3 * x
9 = 3x
Divide both sides by 3:
9 / 3 = x
3 = x
Therefore, Lisa should add 3 tsp of baking soda to 9 lbs. of flour. Thus, the correct option 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.
The ratio of baking soda to flour in the first scenario is 2 tsp:6 lbs.
To find out how much baking soda to use 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, we have:
6x = 18
Dividing both sides of the equation by 6, we find:
x = 3
Therefore, Lisa should add 3 tsp of baking soda to 9 lbs. of flour.
The answer is option 1: 3 tsp.
To find out how much baking soda Lisa should add to 9 lbs. of flour, we need to consider the ratio of baking soda to flour.
In this case, we know that Lisa added 2 tsp of baking soda to 6 lbs. of flour. To find the ratio, we can express this as a fraction: (2 tsp / 6 lbs).
Now, we can set up a proportion to solve for the unknown amount of baking soda:
(2 tsp / 6 lbs) = (x tsp / 9 lbs)
To solve for x, we can cross-multiply:
6 lbs * x tsp = 2 tsp * 9 lbs
Now, let's calculate the value of x:
6x tsp = 18 tsp
To isolate x, let's divide both sides of the equation by 6:
x tsp = 18 tsp / 6
Simplifying, we find:
x tsp = 3 tsp
Therefore, Lisa should add 3 tsp of baking soda to 9 lbs. of flour.
The correct option is: 3 tsp.
