The fuel for a chain saw is a mix of oil and gasoline. The ratio of ounces of oil to gallons of gasoline is \( 5: 18 \). There are 36 gallons of gasoline. How many ounces of oil are there? 129.6 ounces 2.5 ounces 10 ounces 16 ounces

To find out how many ounces of oil are needed, we can use the given ratio of oil to gasoline, which is \( 5:18 \). This means for every 5 ounces of oil, there are 18 gallons of gasoline. Given that there are 36 gallons of gasoline, we can set up a proportion: \[ \frac{5 \text{ ounces of oil}}{18 \text{ gallons of gasoline}} = \frac{x \text{ ounces of oil}}{36 \text{ gallons of gasoline}} \] Cross-multiplying gives us: \[ 5 \times 36 = 18 \times x \] This simplifies to: \[ 180 = 18x \] Dividing both sides by 18: \[ x = 10 \text{ ounces of oil} \] So, the answer is 10 ounces. Now, here‘s a little extra info: In many chainsaw usage scenarios, that oil-gas mixture is crucial for keeping the engine lubricated while you tackle those yard demands! If you mix it right, it's less likely to clog and will keep your chainsaw running like a dream. And let’s not forget that proper maintenance and refueling can drastically increase the lifespan of your chainsaw. Regularly check your oil and gas mixture and ensure they're properly stored to avoid any mishaps while you're out trimming those branches. Happy sawing!
