To solve the equation -2/5t = -8/3, you want to isolate the variable t. Here's how you can do it:

Step 1: Multiply both sides of the equation by the reciprocal of -2/5, which is -5/2. This will cancel out the coefficient on t.
(-5/2) * (-2/5t) = (-5/2) * (-8/3)

Step 2: Simplify both sides of the equation.
1t = 8/3 * 5/2

Step 3: Perform the multiplication.
t = 40/6

Step 4: Simplify the fraction (if needed).
t = 20/3

So, the solution to the equation -2/5t = -8/3 is t = 20/3.
