Answer:
As per the statement:
The formula to convert Fahrenheit to Celsius is:
[tex]C = \frac{5}{9}(F-32)[/tex] .....[1]
where, C is the Celsius and F is the Fahrenheit.
We have to convert 18 degree Celsius to Fahrenheit.
C = 18 degree
Substitute the value of C in [1] we have;
[tex]18= \frac{5}{9}(F-32)[/tex]
multiply both sides by [tex]\frac{9}{5}[/tex] we have;
32.4 = F -32
Add 32 to both sides,
32.4+32 = F -32+32
Simplify:
64.4 = F
or
F = 64.4 degree
Therefore, conversion of 18 degree Celsius in Fahrenheit to the nearest degree is, 64 degree F.
