F = ⁹/₅ C + 32 Plug in the values given in the problem. We know that the temperature is 40°C, so we plug it into the equation where the C is. In this problem, we are solving for "F." F = ⁹/₅ (100) + 32 Follow order of operations to solve: F = ⁹/₅ (100) + 32 We can see that the variable "F" is already isolated. so all we have to do is follow order of operations to solve. First, perform the multiplication step on the right hand side. Remember that when multiplying a whole number by a fraction, convert the whole number to a fraction by making the whole number the numerator and 1 the denominator. F = ⁹/₅ (100) + 32 F = ⁹/₅ • ¹⁰⁰/₁ + 32 F = ⁹⁰⁰/₅+ 32 Remember that the fraction line signals division, so we can simplify this by dividing the 900 by 5. F = 180 + 32 Finally, add the two remaining values together. F = 212
