Lisa adds 2 tsp baking soda to 6 lbs. of flour. How much baking soda should she add to 9 lbs. of flour?

Answer 1

To find out how much baking soda Lisa should add to 9 lbs. of flour, we need to set up a proportion based on the ratio of baking soda to flour.

The ratio of baking soda to flour is 2 tsp : 6 lbs.

Let x represent the amount of baking soda Lisa should add to 9 lbs. of flour.

Using the proportion, we can set up the equation:

2 tsp / 6 lbs = x tsp / 9 lbs.

Cross-multiplying, we get:

(2 tsp) * (9 lbs) = (6 lbs) * (x tsp)

18 tsp = 6 lbs * x tsp

Dividing both sides of the equation by 6 lbs, we get:

18 tsp / 6 lbs = x tsp

3 tsp = x tsp

Therefore, Lisa should add 3 tsp of baking soda to 9 lbs of flour.
