• Parts per million (ppm) as a ratio or fraction • Converting ounces to pounds to compare like units • Setting up a proportion: amount of vanadium vs. total fuel weight

💭 Think About

• How can you express 10 ounces of vanadium as a fraction of 3125 pounds of fuel, making sure both are in the same units? • Once you have that fraction, how do you convert it into parts per million (ppm)? • After finding the ppm, how does it compare to the manufacturer’s 300 ppm recommendation?

✅ Before You Answer

• Convert ounces to pounds correctly before doing any ppm calculation. • Check that your ppm value is the ratio (vanadium/total fuel) multiplied by 1,000,000. • Compare your calculated ppm with 300 ppm to decide if it is below, near, or above the recommended limit.
