Question

In the formula I=prt, what is the value of t

Answer 1

You divide both sides by pr to get t on one side.
1=prt
= 1/pr=t
So the answer is one as the numerator and pr as the denominator
1/pr

Answer 2

1) Hmm... divide everything by t:
1 = prt | ÷t
1/t = prt/t
1/t = pr
2) Switch places between "pr" and "t":
1/t = pr
t = 1/pr
That's the answer....
