Lis adds 2 tsp of baking soda to 6lbs of flour. how much baling soda should she add to 9 lbs of flour
To find out the amount of baking soda Lis should add to 9 lbs of flour, we can set up a proportion based on the given information.
The ratio of baking soda to flour is 2 tsp to 6 lbs.
Let x be the amount of baking soda to be added to 9 lbs of flour.
So, we can set up the proportion as:
2 tsp / 6 lbs = x tsp / 9 lbs
Cross-multiplying, we get:
2 tsp * 9 lbs = 6 lbs * x tsp
18 tsp-lbs = 6x tsp
Dividing both sides by 6 to isolate x, we get:
18/6 tsp-lbs = x tsp
3 tsp-lbs = x tsp
Therefore, Lis should add 3 tsp of baking soda to 9 lbs of flour.
