To find out how much oil Randi will need for 8 gallons of gas, we need to use the ratio of 5 gallons of gas to 2 gallons of oil.
First, let's set up a proportion to solve for the unknown amount of oil (let's call it "x") that Randi will need:
5 gallons of gas / 2 gallons of oil = 8 gallons of gas / x gallons of oil
Next, we can cross-multiply and solve for x:
5 * x = 8 * 2
5x = 16
Divide both sides of the equation by 5 to isolate x:
x = 16 / 5
x = 3.2
Therefore, Randi will need 3.2 gallons of oil for 8 gallons of gas.
For every 5 gallons of gas, Randi will need 2 gallons of oil.
So, for 8 gallons of gas, Randi will need:
8 / 5 * 2 = 16/5 = <<8/5=1.6>>1.6 gallons of oil.
Therefore, Randi will need 1.6 gallons of oil.
To determine how much oil Randi will need for 8 gallons of gas, we can use the given ratio of 5 gallons of gas for every 2 gallons of oil.
First, we need to find the equivalent ratio for 8 gallons of gas. Since 8 is double of 4, we can say that 8 gallons of gas is equivalent to 2*2 = 4 multiples of the given ratio.
Next, we multiply the number of multiples (4) by the amount of oil in each multiple (2 gallons) to find the total amount of oil needed.
4 * 2 gallons = 8 gallons of oil.
Therefore, Randi will need 8 gallons of oil for 8 gallons of gas.
the answer is 2.3
