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.
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:
5/2 = 8/x
To solve for x (the amount of oil), we can cross-multiply:
5x = 2 * 8
5x = 16
Dividing both sides of the equation by 5:
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 mixture ratio.
The ratio given is 5 gallons of gas for every 2 gallons of oil. This means that for every 5 gallons of gas, we need 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 = 2 * 8
5x = 16
Dividing both sides by 5, we find:
x = 16 / 5
To express the answer in tenths, we divide 16 by 5:
x ≈ 3.2
Therefore, Randi will need approximately 3.2 gallons of oil for 8 gallons of gas.
Apologies for the incorrect response. Let's solve the problem correctly:
The given ratio is 5 gallons of gas for every 2 gallons of oil. We can set up a proportion to find out how much oil Randi will need for 8 gallons of gas:
5 gallons of gas / 2 gallons of oil = 8 gallons of gas / x gallons of oil
Cross-multiplying, we get:
5x = 2 * 8
5x = 16
Dividing both sides by 5:
x = 16 / 5
To express the answer in tenths, we can divide 16 by 5:
x ≈ 3.2
Therefore, Randi will need approximately 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 based on the given ratio:
5 gallons of gas / 2 gallons of oil = 8 gallons of gas / x gallons of oil
To solve for x, we will cross-multiply and then divide:
5 * x = 2 * 8
5x = 16
x = 16 / 5
Calculating this, we find that x is approximately equal to 3.2 gallons of oil. Therefore, Randi will need 3.2 gallons of oil for 8 gallons of gas.
