Answer:
the next step is to multiply the result by 5/9.
Step-by-step explanation:
Below, the formula to convert Farenheit degrees to Celcius.
T(°C) = (T(°F) - 32) × 5/9
If barbara already subtracted 32 from 78, now the next step is to multiply the result by 5/9.
T(°C) = (78°F - 32) × 5/9 → T(°C) = (46) × 5/9 = 25.55°C
