\n" );

document.write( "A cylinder 4 in. in diameter and 6 in. high holds 1 lb of oatmeal. To the nearest ounce, how much oatmeal will a similar 10 in. high cylinder hold?(hint: 1 lb = 16 oz)\r
\n" );

document.write( "First, I tried to put the numbers in proportions such as 4 over the unknown diameter, and 6 in. over 10 in. to find the unknown diameter. The answer I got was 6.6666 and so on, but Im not sure if Im supposed to leave it like that, round it, or leave it as a mixed fraction.\r
\n" );

document.write( "After that, how do I calculate how much oatmeal is in the higher cylinder? I would like it if it can be explained to me clearly because this kind of problem confuses me.\r
