Math Problem for My Blog: Can you figure it out? (Percentages)

I am currently writing a blog post about Michigan's exports.

Anyway, here is the math problem..



PTS & ACCESS OF BODIES OF MOTOR VEHICLES, NESOI account for 8.4% of Michigan's exports.

Michigan's exports account for 3.9% of the US's exports.

What % of the US's exports do PTS & ACCESS OF BODIES OF MOTOR VEHICLES, NESOI account for?

 

Are you sure it's a blog post and not homework?

I think it's 0.3276%

 

Yeah, lol, it's about trade deficit, when it's posted you can read it.
How did you get that? My friend says there's not enough information for it, but I'm pretty sure there is. Math is not my strong suit and whenever I come up with a math problem, it's always on the complex side like my last one about monthly compounding interest rates which I think I asked in November. Shortly after I posted it, we found a calculator which does it for you.

 

He multiplied 3.9 by 0.084

 

Yeah, 0.039 (3.9%) * 0.084 (8.4%) = 0.003276 (0.3276%)

 

His calculation is correct
