Lisa, add 2 teaspoons baking soda to 6 pounds of flour how much baking soda should she add to 9 pounds of flour would it be 27 teaspoons 3 teaspoons 18 teaspoons or 9 teaspoons?
If Lisa adds 2 teaspoons of baking soda to 6 pounds of flour, and she wants to know how much baking soda she should add to 9 pounds of flour, we can set up a proportion:
2 teaspoons / 6 pounds = x teaspoons / 9 pounds.
To solve for x, we can cross-multiply:
2 * 9 = 6 * x,
18 = 6x.
Dividing both sides by 6 gives:
18 / 6 = x,
3 = x.
Therefore, Lisa should add 3 teaspoons of baking soda to 9 pounds of flour.
