Question

The formula to convert Fahrenheit to Celsius is C = 5/9 (F-32). convert 12C to Fahrenheit . Round to nearest degree.

Answer 1

The formula to convert Fahrenheit to Celsius is C = 5/9 (F-32).

convert 12C to Fahrenheit

We replace 12 with C in the formula

$12 = \frac{5}{9} (F-32)$

Now multiply the fraction inside the parenthesis

$12 = \frac{5}{9}F-\frac{5}{9}*32$

$12 = \frac{5}{9}F-\frac{160}{9}$

Add the fraction on both side

$12+\frac{160}{9} = \frac{5}{9}F$

$\frac{108+160}{9} = \frac{5}{9}F$

$\frac{268}{9} = \frac{5}{9}F$

multiply by 9/5 on both sides

$\frac{268}{9} *\frac{9}{5} = F$

$\frac{268}{5} = F$

F= 53.6

So Fahrenheit = 53.6

When we round to nearest degree it becomes 54
