If cement, gravel, and sand are to be mixed in the ratio of 3:5:7 respectively, and 5 tons of cement are available, how many tons of the mixture can be made? (Assume that enough gravel and sand are available to use all the available cement.)

\n" ); document.write( "We can do it this way, let x = the multiplier
\n" ); document.write( "3x:5x:7x
\n" ); document.write( ":
\n" ); document.write( "Find the multiplier using the cement which was given
\n" ); document.write( "3x = 5
\n" ); document.write( "x = $\"5%2F3\"$ is the multiplier
