Example 7.57 from Prealgebra, 7.5 Systems of Measurement

Systems of Measurement: example 7.57

Convert $50 °F$ into degrees Celsius.

Work it out on paper first. Then open the solution one step at a time, and stop as soon as you can finish on your own.

Solution
We will substitute $50 °F$ into the formula to find $C .$

Use the formula for converting °F to °C $C = \frac{5}{9} (F - 32)$

Simplify in parentheses. $C = \frac{5}{9} (18)$

Multiply. $C = 10$

A temperature of 50°F is equivalent to 10°C.

Your turn

The book's Try It right after this example: same idea, new numbers. Only the answer is given.

Convert the Fahrenheit temperatures to degrees Celsius: $59 °F .$
