Question

Frame the formula for the following statement: The Fahrenheit temperature $F$ increased by $42$ is equal to one-fifth of the Centigrade temperature C.

• A. $F-42=\frac{1}{5}C$
• B. $F+42=\frac{1}{5}C$
• C. $F=\frac{1}{5}C+42$
• D. $F=\frac{1}{5}C$

Answer 1

The correct option is B $F+42=\frac{1}{5}C$

Given that Fahrenheit $F$ increased by $42$ is equal to $\frac{1}{5}$ of Centigrade, the formula is
$F+42=\frac{1}{5}C$

So, option B is correct.
