Question

If it is given that $F=\frac{9}{5}C+32$, then the expression for $C$, is equal to

• A. $\frac{5}{9}(F+32)$
• B. $\frac{9}{5}(F-32)$
• C. $\frac{5}{9}(F-32)$
  
• D. $\frac{9}{5}(F+32)$
  

Answer 1

The correct option is C $\frac{5}{9}(F-32)$

Given:

$F=\frac{9}{5}C+32$

$\Rightarrow F-32=\frac{9}{5}C$

Multiply both side with $\frac{5}{9}$, we get

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

Hence, option C.
