Final answer:
To solve for t in the equation 1/3 = 2/t, cross-multiply and simplify to find that t = 6.
Step-by-step explanation:
To solve for t in the equation 1/3 = 2/t, we can cross-multiply. Multiplying both sides of the equation by t, we get 1t = 2(3). Simplifying, we have t = 6/1 = 6. Therefore, the number that could replace t is 6.
