tolong dijalankan besok dikumpulkan...

1. C = 40
R = 4/5 x 40
= 32 derajat

F = (9/5 x 40) + 32
= 72 + 32
= 104 derajat

2. R = 40
F = (9/4 x 40) + 32
= 90 + 32
= 122 derajat

C = 5/4 x 40
= 50 derajat

3. F = 50
C = 5/9 x (50-32)
= 5/9 x 18
= 10 derajat

R = 4/9 x (50-32)
= 4/9 x 18
= 8 derajat

4. C = 60
R = 4/5 x 60
= 48 derajat

F = (9/5 x 60) + 32
= 108 + 32
= 140 derajat
