45.7°f = what in celsius

Is this the equation I should be using

C = °F-32/1.8
C= 45.7-32/1.8= 7.6

also

45.7 = what is it in absolute scale
1.8(°c) =°F-32
°F= 1.8(°c) +32
°F= 1.8(47.5)+32=  117.5

The first part seems to be solved right, although it would look better algebraically with another set of parentheses...

The second part isn't. What is absolute temperature?

In the first part you have correctly calculated that 45.7°F is the same temperature as 7.6°C.

In the second part you have calculated that 47.5°C is the same as 117.5°F.  (Note 45.7°C = 114.26°F)

But the question in the second part was not "45.7 = what is it in Fahrenheit scale", but "45.7 = what is it in absolute scale"

[Borek]

It is not clear to me if the answer should be given using Kelvin, or Rankine scale. As long as the scale is clearly stated I would accept both answers.

Not that the correct answer in any scale was given so far.

In the second case - convert to Celsius then to Fahrenheit

But the question in the second part was not "45.7 = what is it in Fahrenheit scale", but "45.7 = what is it in absolute scale"

Which is why I gave the answer I did to point out that the calculation that the OP had made converted 47.5°C into °F which was clearly not the question asked.

Although what exactly the question being asked was is far from clear as "45.7 = what is it in absolute scale?" is a meaningless half question it could be any of these

45.7°F what is it on the Rankine scale?
45.7°C what is it on the Rankine scale?
45.7K what is it on the Rankine scale?
45.7°F what is it on the Kelvin scale?
45.7°C what is it on the Kelvin scale?
45.7°R what is it on the Kelvin scale?

The OP needs to present a single defined actual question to get any further help.
