25\times \frac{9}{5}=F-32
Multiply both sides by \frac{9}{5}, the reciprocal of \frac{5}{9}.
\frac{25\times 9}{5}=F-32
Express 25\times \frac{9}{5} as a single fraction.
\frac{225}{5}=F-32
Multiply 25 and 9 to get 225.
45=F-32
Divide 225 by 5 to get 45.
F-32=45
Swap sides so that all variable terms are on the left hand side.
F=45+32
Add 32 to both sides.
F=77
Add 45 and 32 to get 77.
