Question

Convert 72°F to °C (to the nearest tenth) using one of the following formulas: F = 9/5xC + 32 or C = (F - 32) x 5/9.

Answer 1

First set up the equation:
$C=(F-32)\times\frac{5}{9}$
Then substitute in known values:
$C=(72-32)\times\frac{5}{9}$
and solve for C
$C=40\times\frac{5}{9}$
$C=22.22$

Answer 2

If you would like to convert 72°F to °C using one of the following formulas, you can do this using the following steps:

C = (F - 32) * 5/9
C = (72 - 32) * 5/9
C = 40 * 5/9 
C = 22.2°C

The correct result would be 22.2°C.
