Answer:
6.5 teaspoons or 13/2
Step-by-step explanation:
there are 2 teaspoons per 13 teaspoons of salt. if you only use 1 teaspoons of baking powder you will cut the amount of salt in half. Half of 13 is 6.5 therefore you will need 6.5 teaspoons... depending on how you chose to simplify ur answer it may be different.
