There are 2 ways to do this problem.
\n" ); document.write( "1. Cross multiplication
\n" ); document.write( " OR
\n" ); document.write( "2. Equivalent fractions\r
\n" ); document.write( "\n" ); document.write( "So let's do Method 1 first.\r
\n" ); document.write( "\n" ); document.write( "To do cross multiplication, you multiply the 2 known values diagonal from each other, then divide it by the remaining known value. This method is most useful when when trying to determine unknown values in fractions. \r
\n" ); document.write( "\n" ); document.write( "So the question would look like this. 4/5=24/x
\n" ); document.write( "Then, you would make a that looks like this: x=5*24 divided by 4
\n" ); document.write( " x=30
\n" ); document.write( "Method 2
\n" ); document.write( "4*6=24
\n" ); document.write( "so
\n" ); document.write( "5*6=30\r
\n" ); document.write( "\n" ); document.write( "Therefore, when full, the gas tank can hold 30 gallons.
