Step 1: Determine which formula to use.
Since we are given Celsius and are solving for Fahrenheit
we will use the following formula:
(°C × 1.8) + 32 = °F
Step 2: Substitute in the provided temperature.
We are going to use the formula from Step 1, and insert
the temperature we were given.
(21.4 °C × 1.8) + 32 = °F
Step 3: Solve following the order of operations.
Following PEMDAS, we simplify what’s in the parentheses
first.
(21.4 °C × 1.8)
So this is what happens:
(21.4 °C × 1.8) + 32 = °F
Becomes:
38.52 + 32 = °F
We could drop the parentheses since we completed the
operation inside of them.
Now we can solve the problem.
38.52 + 32 = °F
70.52 = °F
