Question

convert the temperature from degrees fahrenheit to degrees celsius, using the formula below. c = \frac{5}{9}×(f - 32) round your answer to the nearest degree. 170°f = °c

Explanation:

Step1: Substitute F value

Substitute $F = 170$ into the formula $C=\frac{5}{9}\times(F - 32)$. So we get $C=\frac{5}{9}\times(170 - 32)$.

Step2: Calculate the value in parentheses

First calculate $170-32 = 138$. Then the formula becomes $C=\frac{5}{9}\times138$.

Step3: Multiply and round

$C=\frac{5\times138}{9}=\frac{690}{9}\approx77$.

Answer:

77
