Andy is mixing blue, green and white paint in a 1 : 2 : 5 ratio. If he uses 6 gallons of green paint, how many gallons of paint does he use total?
assistant
How many gallons of blue paint does Andy use? ** First find the number of gallons of blue paint by multiplying the gallons of green paint by the ratio between the blue and green paint: 1 blue gallon/2 green gallons * 6 gallons = 3 gallons
How many gallons of white paint does Andy use? ** Then find the number of gallons of white paint by multiplying the gallons of green paint by the ratio between the white and green paint: 5 white gallons/2 green gallons * 6 gallons = 15 gallons
How many gallons of paint does Andy use? ** Then add the number of gallons of each color to find the total number of gallons of paint: 6 gallons + 3 gallons + 15 gallons = <<6+3+15=24>>24 gallons
