Question

Can someone pls help explain how they came up with this equation:
212F=__C
C=5/9 C-32
C=5/9(212)-32
C=5/9(180)
C=100
So 212F = 100C
any help thnks.

Answer 1

I think it works this way

\[C = \frac{5}{9} \times (212 - 32)\]

order of operation says brackets 1st

\[C = \frac{5}{9} \times 180\]

\[C = \frac{900}{9} \]

C = 100

Answer 2

ok but how did you get 900

Answer 3

what made you go from 180 to 900

Answer 4

180 x 5 = 900

Answer 5

k

Answer 6

5/9 x 180 = (5 x 180)/9

Answer 7

did you set 5/9 x 180 up as a fraction that needed to be reduced

Answer 8

5/9 x180/1

Answer 9

I did so you could see the steps... normally I'd type it into a calculator as I've written it at the start

5/9 x(212 - 180)

Answer 10

no you don't need both as fractions
