Question

Peter has just learned that to change from Fahrenheit to Celsius, he needs to subtract 32 from the Fahrenheit temperature and then multiply by 5/9. Which of the following formulas can be used to change from Fahrenheit to Celsius?

Answer 1

EXPLANATION

Let's see the facts:

°F -----> °C (What we need to do)

Steps:

1) Subtract 32, so we must do it with the °F as following:

F - 32

2) Multiply by 5/9, so we must do it with the (F - 32) as following:

(F - 32)*(5/9)

The formula that can be used to change from Fahrenheit to Celsius is:

C = 5/9(F - 32) [OPTION D]
