Question

Jack's pancake recipe calls for 2 tsp baking powder and 3 c of flour.

Answer 1

Answer:

6 tsp baking powder is needed if Jack uses 9 c of flour.

Step-by-step explanation:

Given : Jack's pancake recipe calls for 2 tsp baking powder and 3 c of flour.

To find : How much baking powder is needed if Jack uses 9 c of flour.

Solution :

For 3 c of flour baking powder needed = 2 tsp

For 1 c of flour baking powder needed = $\frac{2}{3}$ tsp

Now, we have to find the amount of baking powder needed in 9 c flour.

For 9 c of flour baking powder needed = $\frac{2}{3}\times 9$ tsp

                                                                  =  6 tsp

Therefore, 6 tsp baking powder is needed if Jack uses 9 c of flour.

Answer 2

6 tps baking powder. For every 3, there is two. 3 multiplied by 2 is 6.
