Question

convert the temperature from degrees fahrenheit to degrees celsius, using the formula below.

c = \frac{5}{9} \times (f - 32)

149°f = \square°c

Explanation:

Step1: Substitute the Fahrenheit value into the formula

Substitute \(F = 149\) into \(C=\frac{5}{9}\times(F - 32)\). So we get \(C=\frac{5}{9}\times(149 - 32)\).
First, calculate the value inside the parentheses: \(149-32=117\). Then the formula becomes \(C=\frac{5}{9}\times117\).

Step2: Calculate the Celsius value

Since \(\frac{5}{9}\times117=\frac{5\times117}{9}\), and \(117\div9 = 13\), then \(5\times13 = 65\).

Answer:

\(65\)
