document.write( "The proportion expresses very simple idea that the \"rate of work\" of each truck is the same, measured in tons per truck per day.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "From the proportion,  find  x =  = 12*7*3 = 252 tons.    ANSWER\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "By doing in this way, you have easy way to create an equation (a proportion) based on clear idea of the rate of work.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "So, you will never make a mistake using this method.\r\n" );

document.write( "    If 5 trucks transport 120 tons in 2 days, then it is clear than 1 truck transports   =  = 12 tons per day.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "    Therefore, you need simply multiply these 12 tons by 7 and 3 to get the answer  12*3*7 = 252 tons.\r\n" );
