Find the Fahrenheit equivalent of 55 Celsius. Solution We\'ll note: F = Fahrenheit temperature C = Celsius temperature We\'ll uset the conversion formula and we\'ll substitute 55 for Celsius. C = (5/9)(F-32) 55 = (5/9)(F-32) We\'ll multiply by (9/5): 55*9/5 = F - 32 We\'ll simplify and we\'ll get: 11*9 = F - 32 99 = F - 32 We\'ll add 32 both sides: F = 99 + 32 F = 131 Fahrenheit are the equivalent of 55 degrees Celsius..
