Lisa adds 2 tsp baking soda to 6 Ibs. of flour. How much baking soda should she add to 9 lbs. of flour? (1 point)
• 3 tsp
• 18 tsp
O9 tsp
O 27 tsp
To find the amount of baking soda to 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 = 6x
Dividing both sides by 6, we find:
3 tsp baking soda = x
Therefore, Lisa should add 3 tsp of baking soda to 9 lbs. of flour.
Answer: 3 tsp.
