Answer:

5/6

Step-by-step explanation:

Since 1/3÷2/5 can also be written as 1/3/2/5

So the ÷ can then be converted to × and 2/5 will change to 5/2

So let's solve

1/3×5/2

5/6

Since there is no common number that can divide the two

So the final answer is 5/6

                 -------- .  Invert --------- and multiply ---------- by the result:
                  8x^2                 (x^2)                         8x^2

                5t^2
multiply ---------- by the result:      5t^2       5*x^2     25 t^2 x^2
                8x^2                            ------- * ---------  = ----------------
                                                    8x^2         3t         8x^2 (3t)

Reducing this, we get       25t
