Ni’Kieylah uses 3 cups of sugar for every 2 teaspoons of baking soda to make a batch of cookies. Which proportion could be solved to find x, the number of teaspoons of baking soda needed for 9 cups of sugar?(
3 cups sugar = 2 teaspoons baking soda
9 cups sugar = x teaspoons baking soda
This can be set up as a proportion:
3/2 = 9/x
Cross multiply to solve for x:
3x = 18
x = 6
Therefore, Ni’Kieylah would need 6 teaspoons of baking soda for 9 cups of sugar.
