F = ⁹/₅ C + 32 Plug in the values given in the problem. We know that the temperature is 40°F, so we plug it into the equation where the F is. In this problem, we are solving for "C." 40 = ⁹/₅ C + 32 Follow order of operations to solve: 40 = ⁹/₅ C + 32 First, subtract the 32 from both sides to begin isolating the variable "C". 40 - 32 = ⁹/₅ C - 32 Next, divide both sides by ⁹/₅in order to completely isolate the variable "C". Remember that when you divide by a fraction, you flip the fraction and multiply. 8 = ⁹/₅ C 8 •⁵/₉ = ⁹/₅ • ⁵/₉ C When multiplying a whole number by a fraction, remember to convert the whole number to a fraction by making the whole number the numerator and 1 the denominator. ⁸/₁ •⁵/₉ = ⁴⁰/₉ Finally, convert the fraction to a decimal by dividing the numerator by the denominator (remember that the fraction line represents division). 40 ÷ 9 = 4.4444 Round to the nearest tenth. 4.44 = C Answer: 40°F is equal to 4.44°C
