Randi needs to mow her lawn. The mixture requires 5 gallons of gas for every 2 gallons of oil. How much oil will she need for 8 gallons of gas? Your answer should be in tenths. (1 point)
To find out how much oil Randi will need for 8 gallons of gas, we can set up a proportion.
If 5 gallons of gas requires 2 gallons of oil, then 8 gallons of gas will require x amount of oil.
Using cross products, we get:
5/2 = 8/x
Cross-multiplying, we get:
5x = 2 * 8
5x = 16
Dividing both sides by 5, we get:
x = 16/5 = 3.2
Therefore, Randi will need 3.2 gallons of oil for 8 gallons of gas.
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 for every 2 gallons of oil:
5 gallons of gas / 2 gallons of oil = 8 gallons of gas / x gallons of oil
Cross multiply to solve for x:
5x = 8 * 2
5x = 16
Divide both sides by 5:
x = 16 / 5
x = 3.2
Therefore, Randi will need 3.2 gallons of oil for 8 gallons of gas.
To find out 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 can set up a proportion to find the amount of oil needed. Let x represent the amount of oil in gallons:
5 gallons of gas / 2 gallons of oil = 8 gallons of gas / x gallons of oil
Cross-multiplying, we get:
5x = 8 * 2
5x = 16
Dividing both sides of the equation by 5, we find:
x = 16 / 5
x = 3.2
Therefore, Randi will need 3.2 gallons of oil for 8 gallons of gas.
