Randy needs to mow her lawn the mixture requires 5 gallons of gas for every 2 gallons of oil how much oil she need for 8 gallons of gas your answer should be in tenths

Answer 1

To determine how much oil Randy needs for 8 gallons of gas, we start with the ratio of gas to oil provided:

5 gallons of gas requires 2 gallons of oil.

Now, let's find out how many gallons of oil are needed for 8 gallons of gas.

We can set up a proportion based on the original ratio:

\[ \frac{5 \text{ gallons of gas}}{2 \text{ gallons of oil}} = \frac{8 \text{ gallons of gas}}{x \text{ gallons of oil}} \]

Cross-multiply to find \(x\):

\[ 5x = 8 \times 2 \]

Calculating the right side:

\[ 5x = 16 \]

Now, divide both sides by 5 to solve for \(x\):

\[ x = \frac{16}{5} = 3.2 \]

So, Randy needs 3.2 gallons of oil for 8 gallons of gas, which is already in tenths (3.2).
