Question

Convert 45 degrees Fahrenheit to Celsius. Use the formula F-32= 45 divided by 1.8.

A. 7.2°C
B. 0.2°C
C. 15°C
D. -4.4°C

Answer 1

To convert 45 degrees Fahrenheit to Celsius, subtract 32 from 45 and divide by 1.8, giving approximately 7.2°C. Therefore, option A is the correct answer.

Step-by-step explanation:

To convert 45 degrees Fahrenheit to Celsius, we can use the provided formula F - 32 = C/1.8, where F represents the temperature in Fahrenheit and C represents the temperature in Celsius. We subtract 32 from 45 and then divide the result by 1.8 to find the temperature in Celsius.

Following these steps:

Subtract 32 from 45, which gives us 45 - 32 = 13.

Next, divide 13 by 1.8 to convert to Celsius. Doing the calculation, 13 / 1.8 = 7.22°C (rounded to two decimal places).

Therefore, 45°F is approximately 7.2°C, which makes option A the correct answer.
