Convert 58°F to degrees Celsius.

Question

If necessary, round your answer to the nearest tenth of a degree.
Here are the formulas.
=C5/9−F32

=F+9/5C add 32

Please help

Answer 1

Now let me see

in F, 32 to 212 = freeze to boil
in C, 100 = freeze to boil
so
change of 180 F is change of 100 C
so
change of F = (180/100) change of C = 9/5
now when C = 0, F = 32
so F = 32 + (9/5) C

that settled, what is 52 F
52 = 32 +(9/5) C
20 = (9/5) C
C = 100/9 = 11.1 deg C
