• Temperature conversion between Fahrenheit and Celsius • The relationship between a difference in Fahrenheit degrees and a difference in Celsius degrees • How to use the exact conversion formula vs. simple estimation

💭 Think About

• First, convert 180°F to °C using the standard formula; write it out and work step by step. • After you get the Celsius value, look at each choice and see which is numerically closest to your converted value. • Check whether you are converting the actual temperature (180°F) and not just the difference from another point like freezing or boiling.

✅ Before You Answer

• Use the correct formula: subtract 32 before multiplying by the fraction, not after. • Be sure you’re using the factor 5/9 when going from Fahrenheit to Celsius (and not 9/5). • After conversion, compare the result to the choices and verify which one is closest in value, not just which one 'looks right'.
