Step-by-step explanation:
The answer would be 15000, be cause it is more than half a thousand so it would round up a thousand making it 15 thousand.<span />
Okay, so first, lets determine whether or not these are equivalent, which will lead us to our answer.
8/12 < lets simplify this
8/4 = 2
12/4 = 3
8/12 = 2/3
10/25
10/5 = 2
25/5 = 5
10/25 = 2/5
2/5 ≠ 2/3
These ratios are not proportional.
