A recipe for biscuits calls for ⅓ teaspoon baking powder per 1 ¼ cups of flour. What is the unit rate for baking powder and flour?

Answer 1

if you want baking powder : flour, then that would be
1/3 tsp : 5/4 c
since each cup is 16 tbsp or 48 tsp, that makes it
1/3 tsp : 60 tsp
1 : 180

I've never seen a recipe that uses so little baking powder.
