The answer is A please Mark as brainless
This is fairly simple. Divide 2,871,000 by 10 and that's your answer!
![\frac{2,871,000}{10} =287,100](https://tex.z-dn.net/?f=%20%5Cfrac%7B2%2C871%2C000%7D%7B10%7D%20%3D287%2C100)
Also, since you're dividing by a factor of 10 (or in this case, <em>10</em>) you can just take away as many places as are zeros in the number you're dividing from. This works for <em>10, 100, 1,000, 10,000, etc. </em>In this case, since there is only one zero in 10 you only take away one place marking, which gives you 287,100.
