Question

convert 88 degrees fahrenheit to degrees celsius.
convert 75 degrees fahrenheit to degrees celsius.
convert 15 degrees celsius to degrees fahrenheit.
convert -5 degrees celsius to degrees fahrenheit.
use °f = 1.8(°c)+32 formula and show your work.

Explanation:

Step1: Recall conversion formula

The formula to convert Celsius ($C$) to Fahrenheit ($F$) is $F = 1.8C+32$, and to convert Fahrenheit to Celsius, we can re - arrange it as $C=\frac{F - 32}{1.8}$.

Step2: Convert 88°F to °C

$C=\frac{88 - 32}{1.8}=\frac{56}{1.8}\approx31.11$ °C

Step3: Convert 75°F to °C

$C=\frac{75 - 32}{1.8}=\frac{43}{1.8}\approx23.89$ °C

Step4: Convert 15°C to °F

$F=1.8\times15 + 32=27+32 = 59$ °F

Step5: Convert - 5°C to °F

$F=1.8\times(-5)+32=-9 + 32=23$ °F

Answer:

88°F is approximately 31.11°C
75°F is approximately 23.89°C
15°C is 59°F

• 5°C is 23°F
