This is a ratio/proportion problem. We know that 5 bags of sugar make 1,500 cookies. So, how many bags of sugar would you need to make 12,000 cookies? We can write that as a proportion: 5: 1,500 :: x: 12,000 Step 1: Rewrite the proportion as a fraction. ⁵⁄_1,500 = ^x⁄_12,000 Step 2: Cross multiply. 5 • 12,000 = 1,500 • x Step 3: Simplify. 5 • 12,000 = 1,500 • x 60,000 = 1,500x Step 4: Simplify by dividing both sides of the equation by 1,500. 60,000 ÷ 1,500 = 1,500x ÷ 1,500 40 = x
