Answer:
x = 10
Step-by-step explanation:
Given the ratio, 5:6, which is also the same as ⅚. In order to solve for the unknown value, x, we can establish the following proportion:
Perform cross-multiplication:
6x = 60
Divide both sides by 6:
x = 10
In order to verify its validity, substitute the value of x into the original proportion:
Perform cross-multiplication:
10 × 6 = 5 × 12
60 = 60 (True statement).
Therefore, the value of x = 10.

This is fairly simple. Divide 2,871,000 by 10 and that's your answer!
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.
