ANSWER
[tex]T = \frac{3W}{S}[/tex]
EXPLANATION
The given formula is
[tex]W = \frac{1}{3} TS[/tex]
We want to solve for T in the given formula.
We multiply through by 3 first to get,
[tex]3 \times W =3 \times \frac{1}{3} TS[/tex]
We simplify to get,
[tex]3W = TS[/tex]
We now divide both sides by S to get,
[tex] \frac{3W}{S} = \frac{ TS}{S} [/tex]
We simplify to obtain:
[tex] \frac{3W}{S} = T[/tex]
or
[tex] T = \frac{3W}{S}[/tex]
