Bagaimana cara menyelesaikan operasi hitung menggunakan perbandingan pada suhu
Tolong bantu menjawab soal berikut:
(1)celcus =50·
Reamur =
Fahrenheit=
(2)fahrenheit=81·
Celcius =
Reamur =

Answer 1

No 1
C = 50

R = 4/5 x C
R = 4/5 x 50 = 4 x 10 = 40 derajat

F = 9/5 x C + 32
F = 9/5 x 50 + 32
F = 90 + 32 = 122 derajat

nomor 2
F = 81

C = (F-32) x 5/9 
C = (81-32) x 5/9
C = 49 x 5/9
C = 27,23 derajat

R = (F-32) x 4/9
R = (81-32) x 4/9
R = 49 x 4/9
R = 21,78 derajat

Answer 2

1. 50 C = ... R
4(50-0) ÷ 5 = 40 R
50 C = ... F
9(50-0) ÷ 5 = 90 + 32 = 122 F
2. 81 F = ... C
5(81-32) ÷ 9 = 5(49) ÷ 9 = 27,23 C
81 F = ... R
4(81-32) ÷ 9 = 4(49) ÷ 9 = 21,78 R
