Answer 1

oi:gas=9:19

if gas=152 then find oil

ratio and proprtion

oil:gas=9:19=x:152
9:19=x:152
convert to fraction
$\frac{9}{19}=\frac{x}{152}$
multiply both sides by 152
$\frac{1368}{19}=x$
72=x

72 oz of oil

Answer 2

There are 72 gallons of ounces of oil in the fuel

The fuel for a chain saw is a mix of oil and gasoline.

The ratio of ounces of oil to gallons of gasoline is 9:19.

So oil : gas = 9:19

There are 152 gallons of gasoline

⇒ oil : gas = 9:19

Let there are x gallons of ounces of oil

So x : 152 = 9:19

Convert ratio to fraction

⇒ x/152 = 9/19

Multiply both sides by 152

⇒ x = (9/19)152

⇒ x = 72

Hence, there are 72 gallons of ounces of oil in the fuel.
