Question

If the gas to oil ratio of a certain chainsaw is 25 to 1.

a. how much oil(in gallons) should be mixed with 13 gallons of gasoline?

b. If 1 gallon equals128 fluid ounces, write the answer to part a in fluid ounces?

the answers should be:

a.Mix ------- gallons of oil with 13 gallons of gas.

(simplify your answer)

b.approximately ____ fluid ounces of oil should be mixed with 13 gallons of gas?

(round to the nearest whole number as needed)

Answer 1

Since the ratio of gas (G) to oil (O) is 25 to 1, O = G/25

Therefore, if G = 13 gallons, O = (13/25) gallons,

i.e., O = 0.52 gallons  which is about 67 fluid ounces

so .. .

a.Mix about 1/2 gallon of oil with 13 gallons of gas

b.approximately 67 fluid ounces of oil should be mixed with 13 gallons of gas?

Answer 2

13/25 = 0.52 gallons

0.52 gallons X 128 = your answer in fluid oz

Answer 3
