This is how you set up a percent of error proportion:
<u>Amount of error</u> <u>x(Unknown percent)</u>
Actual value = 100(Percents are out of hundreds)
So if you fill it in, it becomes <u>4</u> <u>x
</u> 80 =100
Cross multiply, 400= 80x.
Solve.
x=5 so percent error is 5%<u>
</u>
The value of 2 in 2,783 is 2,000
The value of 2 in 7,283 is 200
2,000 x 200 = 400,000
Hope this helps
