Randi needs to mow her lawn. The mixture requires 5 gallons of gas every 2 gallons of oil. How much oil will she need for 8 gallons of gas? Your answer should be in tenths
According to the given information, the ratio of gas to oil is 5:2.
To find out how much oil is needed for 8 gallons of gas, we need to set up a proportion:
5 gallons of gas / 2 gallons of oil = 8 gallons of gas / x gallons of oil
Cross-multiplying, we get:
5 * x = 8 * 2
5x = 16
x = 16/5
x = 3.2
Therefore, Randi will need 3.2 gallons of oil for 8 gallons of gas.
To determine how much oil Randi will need for 8 gallons of gas, we can use the ratio of 5 gallons of gas to 2 gallons of oil.
First, we need to set up a proportion to find the unknown amount of oil:
5 gallons of gas / 2 gallons of oil = 8 gallons of gas / x gallons of oil
To solve this proportion, we can cross multiply:
(5 gallons of gas) * (x gallons of oil) = (8 gallons of gas) * (2 gallons of oil)
5x = 16
Now, we can solve for x by dividing both sides of the equation by 5:
x = 16 / 5
x ≈ 3.2
Therefore, Randi will need approximately 3.2 gallons of oil for 8 gallons of gas. Remember, the answer is to be expressed in tenths, so the final answer is 3.2 gallons.
To find out how much oil Randi will need for 8 gallons of gas, we can set up a proportion using the given ratio of 5 gallons of gas to 2 gallons of oil.
Let's set up the proportion:
5 gallons of gas / 2 gallons of oil = 8 gallons of gas / x gallons of oil
Cross multiplying, we get:
5 * x = 8 * 2
5x = 16
Dividing both sides by 5, we find:
x = 16/5
Simplifying the fraction, we get:
x = 3.2
Therefore, Randi will need 3.2 gallons of oil for 8 gallons of gas.
