To round a number, you look to the next place to the right of what you want to round to... for example, if you want to round to the nearest hundredth, you look to the thousandths place to see whether the hundredths place rounds up or down.
0.04 is already at the hundredths place so the thousandths place is zero... the answer to the nearest hundredth is 0.04.
For 0.2%, you have to convert the percentage to a decimal by dividing by 100 (move the decimal 2 places to the left).
0.2% = 0.002
So now to round to the nearest hundredth, we look to the thousandths place. The thousandths place has a 2 in it so the hundredths place rounds down. 0.2% total he nearest hundredth is 0.
Answer:
<em>Johnny had </em><em>5</em><em> items and Bobby had </em><em>13</em><em> items.</em>
Step-by-step explanation:
Let us assume that Johnny has x items and Bobby has y items in their list.
Bobby had 3 more than twice as many items on it than Johnny. So,
----------1
Johnny asked for 8 fewer items than bobby. So,
-----------2
Putting the value of x from equation 2 in equation 1, we get
![\Rightarrow y=3+2(y-8)](https://tex.z-dn.net/?f=%5CRightarrow%20y%3D3%2B2%28y-8%29)
![\Rightarrow y=3+2y-16](https://tex.z-dn.net/?f=%5CRightarrow%20y%3D3%2B2y-16)
![\Rightarrow 2y-y=16-3](https://tex.z-dn.net/?f=%5CRightarrow%202y-y%3D16-3)
![\Rightarrow y=13](https://tex.z-dn.net/?f=%5CRightarrow%20y%3D13)
Putting the value of y in equation 2,
![\Rightarrow 13-8=x](https://tex.z-dn.net/?f=%5CRightarrow%2013-8%3Dx)
![\Rightarrow x=5](https://tex.z-dn.net/?f=%5CRightarrow%20x%3D5)
So, Johnny had 5 items and Bobby had 13 items.
