a housekeeper mixed 5 gallons of blue paint with every 9 gallon of yellow paint in order to make a green paint which ratio of gallon of blue paint to gallon of yellow paint will make the same shade of green paint
10 gallons blue to 18 gallons red. to find the answer, multiply/divide both 5 and 9 by the same number. In this case, I multiplied them both by two. 5×2=10, 9×2=18.
