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)
If the mixture requires 5 gallons of gas for every 2 gallons of oil, then the ratio of gas to oil is 5:2.
To find out how much oil Randi needs for 8 gallons of gas, we can set up a proportion:
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 use the ratio given in the problem: 5 gallons of gas for every 2 gallons of oil.
Step 1: Set up a proportion:
5 gallons of gas / 2 gallons of oil = 8 gallons of gas / x gallons of oil
Step 2: Cross multiply:
5 * x = 8 * 2
5x = 16
Step 3: Solve for x:
x = 16 / 5
x = 3.2
Thus, 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 ratio provided: 5 gallons of gas for every 2 gallons of oil.
First, we need to determine the ratio of gas to oil: 5 gallons of gas : 2 gallons of oil.
Next, we can set up a proportion to find the amount of oil needed for 8 gallons of gas:
5 gallons of gas / 2 gallons of oil = 8 gallons of gas / x gallons of oil
Cross-multiplying the ratio, we have:
5 * x = 2 * 8
Now, we can solve for x by dividing both sides by 5:
x = (2 * 8) / 5
x = 16/5
This means that Randi will need 3.2 gallons of oil for 8 gallons of gas.
Therefore, the answer is 3.2 gallons of oil.
