Of the following approximate conversions of Celsius into Fahrenheit, which is most accurate?
kirill [66]

Answer:

option (b) is more accurate.

Step-by-step explanation:

Given some temperature in °C and °F.

We have to check out of given option which is most accurate conversion.

We check of conversion one by one ,

We know the relationship between the temperature in degrees Celsius, C, and degrees Fahrenheit is

F=\frac{9}{5}C+32

1) 24°C and 75.9°F

We substitute the values of degree Celsius and find for degree Fahrenheit.

F=\frac{9}{5}C+32

F=\frac{9}{5}(24)+32

F=75.2

2) 2°C and 35.8°F

We substitute the values of degree Celsius and find for degree Fahrenheit.

F=\frac{9}{5}C+32

F=\frac{9}{5}(2)+32

F=35.6

3) 34°C and 92.7°F

We substitute the values of degree Celsius and find for degree Fahrenheit.

F=\frac{9}{5}C+32

F=\frac{9}{5}(34)+32

F=93.2

4) 13°C and 55°F

We substitute the values of degree Celsius and find for degree Fahrenheit.

F=\frac{9}{5}C+32

F=\frac{9}{5}(13)+32

F=55.4

Thus, out of given options , option (b) is more accurate.
