Question

the fuel for a chain saw is a mix of oil and gasoline. The label says to mix 6 ounces of oil with 16 gallons of gasoline. How much oil would you use if you had 32 gallons of gasoline

Answer 1

You would have to use 12 ounces of gasoline.

Answer 2

Answer:

The answer is 12 ounces.

Step-by-step explanation:

In order to determine the answer, we have to know about directly proportional.

A directly proportional is when two variables are increased at the same time. Both variables have a relation, expressed by a fraction. The fraction is called "constant of proportionality".

In this case, we have:

$\frac{oil}{gasoline}=\frac{6}{16}=\frac{3}{8}$

We always have to fulfil this relation.

Thus, for x: ounces of oil for 32 gallons of gasoline.

$\frac{x}{32}=\frac{3}{8}\\ \\x=\frac{3*32}{8} \\x=12$

Finally, the amount of oil for 32 gallons of gasoline is 12 ounces.
