Question

The​ gas/oil ratio for a certain chainsaw is 50 to 1 .

a. How much oil​ (in gallons) should be mixed with 12 gallons of​ gasoline?

b. If 1 gallon equals 128 fluid​ ounces, write the answer to part a in fluid ounces.

Answer 1

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.
