Answer: celsius = 5/9 (Fahrenheit - 32)
Explanation:
Here, you want to start by looking at the fraction they give you. They say that the degrees celsius (C) are going to be equal to five ninths of (something.)
So, right now, your equation should look like this: C = 5/9 (?) because of stands for multiplication.
Next, you want to figure out what that something is. According to the reading, it'll be the degrees Fahrenheit (F) minus 32. So your something is going to look like this: (F-32)
You know that the equation is C = 5/9 (F - 32) and not C = 5/9 F - 32, because if the 32 were outside the parentheses, the prompt would be written "the temperature in degrees celsius is thirty two less than five ninths of the temperature in degrees Fahrenheit." Instead, the number 32 is explicitly included as part of the number that's being multiplied.
I hope that makes sense!
