You can put this solution on YOUR website!
you have 1,000,000,000 pennies.
\n" ); document.write( "since a dime is equal to 10 pennies, you need to divide the number of pennies by 10 to get the number of dimes.
\n" ); document.write( "1,000,000,000 pennies divided by 10 equals 100,000,000 dimes.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "it's tricky to see when you use variables, but the general idea is:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x = number of dimes
\n" ); document.write( "p = number of pennies
\n" ); document.write( "since a dime is equal to 10 pennies, then:
\n" ); document.write( "10*x = p
\n" ); document.write( "this translates to:
\n" ); document.write( "10 times the number of dimes is equal to the number of pennies.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "you have 30 pennies.
\n" ); document.write( "this makes p = 30
\n" ); document.write( "formula is 10*x = p which becomes:
\n" ); document.write( "10*x = 30
\n" ); document.write( "solve for x to get x = 30/10 = 3\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "in your problem:
\n" ); document.write( "p = 1,000,000,000
\n" ); document.write( "formula is 10*x = p which becomes:
\n" ); document.write( "10*x = 1,000,000,000
\n" ); document.write( "solve for x to get x = 1,000,000,000 / 10 which is equal to 100,000,000\r
\n" ); document.write( "
