Answer:
°F = (9/5 x °C) + 32
Explanation:
Using the upper and lower fixed point as shown in the attached photo, we can obtain the formula for converting from degrees Celsius to degrees Fahrenheit. This is illustrated below:
°C – 0/100 – 0 = °F – 32/212 –32
°C/100 = °F – 32 /180
Cross multiply
100(°F – 32) = 180 x °C
Divide both side by 100
°F – 32 = 180 x °C /100
°F – 32 = 9/5 x °C
Make °F the subject
°F = 9/5 x °C + 32
°F = (9/5 x °C) + 32.
