To find out how much oil Randi needs, you can set up a proportion:
5 gallons of gas / 2 gallons of oil = 8 gallons of gas / x gallons of oil,
where x represents the amount of oil needed for 8 gallons of gas.
To solve for x, you can cross-multiply:
5 * x = 8 * 2,
5x = 16.
Dividing both sides of the equation by 5 gives us:
x = 16 / 5 = 3.2.
Therefore, Randi will need 3.2 gallons of oil for 8 gallons of gas.
5 gallons of gas / 2 gallons of oil = 8 gallons of gas / x gallons of oil,
where x represents the amount of oil needed for 8 gallons of gas.
To solve for x, you can cross-multiply:
5 * x = 8 * 2,
5x = 16.
Dividing both sides of the equation by 5 gives us:
x = 16 / 5 = 3.2.
Therefore, Randi will need 3.2 gallons of oil for 8 gallons of gas.
