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?
3/2 = 9/x
Cross multiply:
3x = 18
Divide by 3 on both sides:
x = 6
Therefore, 6 teaspoons of baking soda are needed for 9 cups of sugar.
