Question
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?
To find the proportion to solve for x, we can use the given ratio that Ni’Kieylah uses 3 cups of sugar for every 2 teaspoons of baking soda.
Let x be the number of teaspoons of baking soda needed for 9 cups of sugar.
Setting up the proportion:
3 cups sugar / 2 teaspoons baking soda = 9 cups sugar / x teaspoons baking soda
Solving for x:
3/2 = 9/x
Cross multiplying:
3x = 18
Dividing by 3:
x = 6
Therefore, Ni’Kieylah would need 6 teaspoons of baking soda for 9 cups of sugar.
