We can use the formula C = \frac{5}{9}(F - 32) to change temperatures in degrees Fahrenheit (F) to temperatures in degrees Celsius (C). The recipe for Grandma's special cake requires the oven set to 350 degrees F. At what temperature should Isabella set her oven to cook Grandma's special cake? Express your answer correct to the nearest degree.

Answer :

To convert the temperature from degrees Fahrenheit to degrees Celsius, we can use the formula:

[tex]C = \frac{5}{9}(F - 32)[/tex]

In this formula, [tex]C[/tex] represents the temperature in degrees Celsius and [tex]F[/tex] represents the temperature in degrees Fahrenheit.

Isabella wants to convert 350 degrees Fahrenheit to Celsius for her Grandma's special cake recipe. Let's follow these steps to find the solution:


  1. Subtract 32 from the Fahrenheit Temperature:

    [tex]F - 32 = 350 - 32 = 318[/tex]


  2. Multiply the Result by [tex]\frac{5}{9}[/tex]:

    [tex]C = \frac{5}{9} \times 318[/tex]


  3. Perform the Multiplication:

    First, multiply 5 by 318:

    [tex]5 \times 318 = 1590[/tex]

    Then, divide the result by 9:

    [tex]C = \frac{1590}{9} \approx 176.67[/tex]


  4. Round to the Nearest Degree:

    Therefore, [tex]C \approx 177[/tex] (rounding to the nearest whole number).



Isabella should set her oven to 177 degrees Celsius to bake Grandma's special cake.
