Converting Fahrenheit to Celsius

Curtis is concerned for his elderly aunt. She recently told Curtis that the temperature where she lives in Australia has been over 45 degrees Celsius all week. How hot is [tex]45^{\circ}[/tex] Celsius when converted to Fahrenheit?

The formula for converting Celsius to Fahrenheit is:
[tex]^{\circ}C \times \frac{9}{5} + 32 = ^{\circ}F[/tex]

A. [tex]89^{\circ}F[/tex]
B. [tex]114^{\circ}F[/tex]
C. [tex]113^{\circ}F[/tex]
D. [tex]102^{\circ}F[/tex]

Answer :

To convert from Celsius to Fahrenheit, we use the formula:

[tex]$$
F = C \times \frac{9}{5} + 32
$$[/tex]

Given that the temperature is [tex]$45^\circ$[/tex] Celsius, we substitute [tex]$C = 45$[/tex] into the formula.

1. Multiply [tex]$45$[/tex] by [tex]$\frac{9}{5}$[/tex]:

[tex]$$
45 \times \frac{9}{5} = 81
$$[/tex]

2. Add [tex]$32$[/tex] to the result:

[tex]$$
81 + 32 = 113
$$[/tex]

Thus, the temperature in Fahrenheit is:

[tex]$$
113^\circ F
$$[/tex]
