0.24 gallons of oil should be mixed with 12 gallons of gasoline.
Therefore, 30.72 fluid ounces of oil should be mixed with 12 gallons of gasoline.
Explanation:
a. To calculate the amount of oil needed, we need to know the ratio of gas to oil in terms of units. Since 50 parts of gas are mixed with 1 part of oil, we have:
1 gallon of gas / 50 = x gallons of oil
To find x, we substitute the given value of gas (12 gallons) and solve for x:
1 gallon of gas / 50 = x gallons of oil
12 gallons of gas / 50 = x
0.24 gallons of oil = x
Therefore, 0.24 gallons of oil should be mixed with 12 gallons of gasoline.
b. To convert gallons to fluid ounces, we multiply by 128:
0.24 gallons of oil * 128 fluid ounces/gallon = 30.72 fluid ounces of oil
Therefore, 30.72 fluid ounces of oil should be mixed with 12 gallons of gasoline.
