Lisa, add 2 tablespoons baking soda to 6 pounds of flour how much baking soda should she had to 9 pounds of flour

To find out how much baking soda should be added to 9 pounds of flour, we can set up a proportion based on the ratio of baking soda to flour.

Ratio of baking soda to flour:
2 tablespoons : 6 pounds

Let's set up the proportion using x as the unknown quantity of baking soda for 9 pounds of flour:

2 tablespoons / 6 pounds = x tablespoons / 9 pounds

Cross-multiplying, we have:

6(x tablespoons) = 2 tablespoons * 9 pounds
6x = 18
x = 18/6
x = 3

Therefore, Lisa should add 3 tablespoons of baking soda to 9 pounds of flour.
