How this it happens???

Question

C = (5/9)(F - 32) C is expressed in terms of F..

5/9)(F - 32) = C
F - 32 = (9/5)C How did 9/5 exist???
F = (9/5)C + 32

Pls explain this step by step........

Answer 1

To get the 5/9 over to the other side, you need to multiply both sides by its reciprocal - 9/5. This will get rid of the 5/9 on the side with the F and leave a 9/5 on the 'C' side.

Answer 2

Example 100 degrees C = 212 degrees F

212 - 32 = 180
Divide by 9 = 20
Multiply by 5 = 100 C

Just for fun try it with -40 C
Surprised?

Answer 3

If you take a temperature reading in degrees Fahrenheit, you can convert it to Centigrade by using your formula.
Take your temperature in Fahrenheit and subtract 32 ( the temp in Fahrenheit that water freezes). Then multiply your answer by 5 and divide that answer by 9. This gives you the same temperature in degrees Centigrade. It is useful for people in another part of the world who use Centigrade to understand what the temp is in the countries that use Fahrenheit. Where did 5/9 come from? Well that I can't tell you. All I know is that It works.

Answer 4

You are aiming to solve the original formula for F.

First, to isolate the variable F, you can multiply both sides of the equation by 9/5, resulting in (9/5)C = F - 32.

Okay, you are now on 3rd base, just about to slide into homeplate......

At this point, to isolate F, simply add 32 to each side, resulting in (9/5)C + 32 = F, just what you were looking for!

Hope that was easy enough to understand! If not, send me a message. I'm willing to offer another way to understand it for you!

Hope this helps! :-)

Answer 5

to move the 5/9 to the other side (to get F by itself) you multiply both sides by the reciprocal which is 9/5. its elementary.

Answer 6

looks like a math question, I don't do math sorry, bye
