tolong dijawab ya pakai cara yang ngerti........makasih

Rumus dari celcius ke
Reamur = (4/5) C
Fahrenheit = (9/5) C + 32

Rumus dari reamur ke
Celcius = (5/4) R
Fahrenhrit = (9/4) R + 32

Rumus dari fahrenheit ke
Celcius = 5/9 (F-32)
Reamur = 4/9 (F-32)

Coba hafalkan rumus diaatas.
Setelah itu mari kita hitung,
1. 40°c = ... °R = ... ° F

R = 4/5 x 40 = 32°R
F = 9/5 x 40 + 32 = 104°f

2. 77°f = ...°C =....°R
R = 4/9 x( 77-32 )= 20°R
C = 5/9 x (77-32) = 25°C

3. 25°C = .....°R =....°F
R = 4/5 x 25 = 20 °R
F = 9/5 x 25+32 = 77°F

4. 44°R = ..°C =....°F
C = 5/4x 44 = 55°C
F = 9/4 x 44+32 = 131°F

5. 60°R = ..°C =....°F
C = 5/4 x 60 = 75 °C
F = 9/4 x 60 + 32 = 167°F
