**Smart Math Methods**Comparison of Temperature

Size Comparison Using Temperature in Celsius, Fahrenheit and Reamur

Those required things considered in comparison of the size of the Celsius temperature, Reamur, Fahrenheit:

- Denoted by C centigrade thermometer, thermometer Reamur symbolized by R, denoted by F. Fahrenheit thermometer
- Comparison of C: R: F [+32] = 5: 4: 9
- When calculating the temperature in Fahrenheit should be added 32 °
- If it comes to calculate the temperature in Fahrenheit to Celsius and 32 ° Reamur be reduced first.

example:

- 60 ° C = ...... ° R = ...... ° F

R = 4/5 X 60 ° = 48 °

F = 9/5 X 60 ° + 32 ° = 140 °

So 60 ° C = 48 ° R = 140 ° F

F = 9/5 X 60 ° + 32 ° = 140 °

So 60 ° C = 48 ° R = 140 ° F

- 50 ° F = ..... ° C = ...... ° R

Smart solution :

C = 5/9 x [50 ° - 32 °] = 5/9 X 18 ° = 10 °

R = 4/9 x [50 ° - 32 °] = 4/9 X 18 ° = 8 °

So 50 ° F = 10 ° C = 8 ° R

C = 5/9 x [50 ° - 32 °] = 5/9 X 18 ° = 10 °

R = 4/9 x [50 ° - 32 °] = 4/9 X 18 ° = 8 °

So 50 ° F = 10 ° C = 8 ° R

- 25 ° C = ..... ° R = ..... ° F

Smart solution :

25 ° C = [4/5 X 25 °] R

4 X 5 = 20 ° R

25 ° C = [9/5 X 25 ° + 32 °] F

[9 X 5] = + 32 ° 77 ° F

25 ° C = [4/5 X 25 °] R

4 X 5 = 20 ° R

25 ° C = [9/5 X 25 ° + 32 °] F

[9 X 5] = + 32 ° 77 ° F

- thermometer shows a temperature of 45 ° Celsius. What is the temperature indicated by a thermometer Reamur and Fahrenheit?

Smart solution :

C = 45 °

C: R: F = 5: 4: 9

R = 4/5 X 45 ° = 36 °

F = 9/5 x 45 ° + 32 ° = 113 °

So 45 ° C = 10 ° R = 113 ° F

Use

C = 45 °

C: R: F = 5: 4: 9

R = 4/5 X 45 ° = 36 °

F = 9/5 x 45 ° + 32 ° = 113 °

So 45 ° C = 10 ° R = 113 ° F

Use

**Easy Methods**Comparison of Temperature Although social math still using way as before.- Temperature american city yesterday 18°C. Today it dropped 3°C. Temperature American city today If Reamur measured using a thermometer and Fahrenheit, is ....

Smart solution :

Temperature american city = 18°C

Decrease in temperature
= 3°C

Temperatures today = 18°C - 3°C = 15°C

Measurement with a thermometer Reamur

15°C = 4/5 X 15°R = 12°R

15°C = [ 9/4 X
15 + 32 ] F = [ 27 + 32 ] F = 59°R

*You can do Test below:*

- Temperature of a meat storage room that is not being used is 25°C.After cooling the machine is turned on for one hour, the room temperature drops by 29°C. so that the temperature reached -16°C, how many degrees the temperature of the room again be lowered ?Answer is 12°C (you prove)
- CelsiusThermometer shows the temperature of 285°. how high the temperature in the show by Reamur and Fahrenheit thermometer ?
- Reamur thermometer shows a temperature of 260°. What is the temperature indicated by a thermometer celcius and fahrenheit?

- daytime temperatures in city A 31°C, at night dropped 12°C. when the morning temperature rises 7°C.What is the temperature in the city in the morning? (try it yourself in your
