Verified step by step guidance1
Recall the formula to convert Fahrenheit (F) to Celsius (C): \( C = \frac{5}{9} (F - 32) \).
Substitute the given Fahrenheit temperature (42 °F) into the formula: \( C = \frac{5}{9} (42 - 32) \).
Calculate the difference inside the parentheses: \( 42 - 32 = 10 \).
Multiply the difference by 5 and then divide by 9: \( C = \frac{5}{9} \times 10 \).
Simplify the expression to find the temperature in degrees Celsius.
