Hello from MrBillDoesMath!
Answer:
.08%
Discussion:
Let the percent be denoted "p". Then
2000 * p% = 160 => ( as p% = p/100)
2000* p/100 = 160 =>
20p = 160 =>
p = 8 or .08%

Answer:
10,100
Step-by-step explanation:
Rounding off to the Nearest hundred is giving a number which ends as 5600 or 6700 etc. To round a number to its nearest hundred you have to first look at the tenths place ( in this case 53) if a number is 50 or above you round it to the next hundred example - 5678 rounded to the nearest hundred is 5700. If a number is below 50 example - 1348, you round it to the same hundred - 1300.
Hope this helps!
