This is a ratio/proportion problem. We know that 50 gallons of pesticide cover 2,000 acres of land. So, how many gallons of pesticide would you need to cover 12,400 acres? We can write that as a proportion: 50: 2,000 :: x: 12,400 Step 1: Rewrite the proportion as a fraction. ⁵⁰⁄_2,000 = ^x⁄_12,400 Step 2: Cross multiply. 50 • 12,400 = 2,000 • x Step 3: Simplify. 50 • 12,400 = 2,000 • x 620,000 = 2,000x Step 4: Simplify by dividing both sides of the equation by 2,000. 620,000 ÷ 2,000 = 2,000x ÷ 2,000 310 = x
