Question

The formula to convert Fahrenheit to Celsius is C=5/9(F-32). Convert 18c to Fahrenheit. Round to the nearest degree

Answer 1

F = [(9/5) * C] +32
F = [(9/5) * 18] +32
F = [32.4] + 32
F = 64.4 degrees

Answer 2

Answer:

As per the statement:

The formula to convert Fahrenheit to Celsius is:

$C = \frac{5}{9}(F-32)$          .....[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;

$18= \frac{5}{9}(F-32)$

multiply both sides by $\frac{9}{5}$ 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.
