Celsius temperature readings can be converted to fahrenheit readings using the formula F+=+%289%2F5%29C%2B32. What is the fahrenheit temperature that corresponds to each of the following celsius temperatures: -10,0,15,100?
For the 1st one, replace the C in

F+=+%289%2F5%29C%2B32

by %28-10%29

F+=+%289%2F5%29%28-10%29%2B32

Write the -10 as %28-10%29%2F1

F+=+%289%2F5%29%28%28-10%29%2F1%29+%2B+32 

Multiply the numerators and denominators

F+=+%28%28-90%29%2F5%29+%2B+32

Reduce the fraction %28-90%29%2F5 to -18

F+=+-18+%2B+32

F+=+14

-------------------------------

For the 2nd one, replace the C in

F+=+%289%2F5%29C%2B32

by %280%29

F+=+%289%2F5%29%280%29%2B32

Since anything time 0 is 0,

F+=+0%2B32

F+=+32

--------------------

For the 3rd one, replace the C in

F+=+%289%2F5%29C%2B32

by %2815%29

F+=+%289%2F5%29%2815%29%2B32

Write the 15 as 15%2F1

F+=+%289%2F5%29%2815%2F1%29+%2B+32 

Multiply the numerators and denominators

F+=+%28135%2F5%29+%2B+32

Reduce the fraction 135%2F5 to 27

F+=+27+%2B+32

F+=+59

------------------------------

For the 4th one, replace the C in

F+=+%289%2F5%29C%2B32

by %28100%29

F+=+%289%2F5%29%28100%29%2B32

Write the 100 as 100%2F1

F+=+%289%2F5%29%28100%2F1%29+%2B+32 

Multiply the numerators and denominators

F+=+%28900%2F5%29+%2B+32

Reduce the fraction 900%2F5 to 180

F+=+180+%2B+32

F+=+212

As F = (9/5)*C + 32.
When C = -10 , F = -18 + 32 = 14
When C = 0, F = 0 + 32 = 32
When C = 10, F = 18 + 32 = 50
When C = 100, F = 180 + 32 = 212
