Question

Please help I gotta find the unknown #

Answer 1

So we are trying to find what multiplied by 10 is 4000. To figure that out, you can just divide 4000 by 10 to get 400. 400 x 10 = 4000.

You can also see from the second line that it says (50 x 8) x 10. So the unknown number is 50 x 8, which is also 400.
