The folrmula F=9/5c+32 can be used to make temperature conversions with the Celsius ans Fahrenheit temperature scales.

F-Fahrenheit temperature

C=Celsius temperature

Convert 100 degress Fahrenheit to the Celsius temperature scale.

Book says answer is 37.78 Celsius

I am not arriving at this answer.

How do you math

Substitute the 100 degrees F

100=9/5C+32

subtract 32 from each side

100-32=9/5C

68=9/5C

68x5/9=C
so
C=37.8

Is this OK. Can you see where you went wrong?

Using your equation F = (9/5) C + 32, which IS the correct equation,

100 = (9/5) C + 32
(9/5) C = 68
C = (5/9)*68 = 37.78 (or 37 7/9)

Thank you for your response

I am not sure where I went wrong. I will review the calculation your provided later.

Your assistance is greatly apreciated.

To convert Fahrenheit to Celsius using the formula F=9/5C+32, you need to rearrange the formula to solve for C (Celsius). Let's go step by step:

1. Start with the given formula: F = (9/5)C + 32
2. Substitute the given Fahrenheit temperature into the formula: F = 100
3. Rearrange the formula to solve for C: 100 = (9/5)C + 32
4. Subtract 32 from both sides of the equation: 100 - 32 = (9/5)C
5. Simplify: 68 = (9/5)C
6. Multiply both sides of the equation by 5/9: (5/9)(68) = C
7. Calculate: 5 * 68 / 9 = C
8. Evaluate the expression to find C: 340 / 9 = 37.78

So, the Celsius temperature equivalent to 100 degrees Fahrenheit is 37.78 degrees Celsius.
