about 15.

To estimate the product or quotient of 5x2 3/5, we can use rounding or compatible numbers.

Rounding involves simplifying the numbers by rounding them to a more manageable value.

For this case, we have 5 multiplied by 2 3/5.

To make it easier, we can round 2 3/5 to 2, as it is close to 2.

Therefore, we have 5 multiplied by 2, which equals 10.

So the estimate of the product is about 10, which matches option A.

Hence, the correct answer is A: about 10.
