Question

What is 29 degrees celsius in fahrenheit?

Answer 1

`color(blue)("Fahrenheit temperature "=(29xx9/5)+32 = 84.2^o F )`

Explanation:

The numbers to remember are 5, 9 and 32

Fahrenheit are the lager number when comparing like temperature for like. So to convert Centigrade to Fahrenheit, you need to make the numbers bigger. Thus you multiply by `9/5`. To go from Fahrenheit to centigrade you are making the numbers smaller so you multiply by `5/9`

All you need to remember now is that freezing point for each is different.

Centigrade freezing point is `0^o`
Fahrenheit freezing point is `32^o`

'~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
`color(blue)("Using this information to answer your question")`

We are going from Centigrade to Fahrenheit so it is small number to large. So we have `color(blue)(xx9/5)`

We are changing freezing point from 0 on 1 scale to 32 on a different scale so we now have:

`color(blue)(xx9/5+32)`

Thus the full conversion is:

`color(blue)("Fahrenheit temperature "=(29xx9/5)+32 = 84.2^o F )`

Answer 2

`"84.2"^@"F"`

Explanation:

An useful formula:

`(""^@"F"-32)/9 = (""^@"C")/5`

So that...

`(""^@"F"-32)/9 = 29/5`

`5xx""^@"F"= 421"`

`""^@"F"= 84.2"`
