5 sheep ate 150 kg of grass in 15 days.
\n" ); document.write( "general formula is n * r * t = q
\n" ); document.write( "n is the number of sheep
\n" ); document.write( "r is the rate that each sheep eats grass
\n" ); document.write( "t is the time
\n" ); document.write( "q is quantity of grass eaten
\n" ); document.write( "when n = 5 and q = 150 kilograms and t = 15 days, the formula becomes:
\n" ); document.write( "5 * r * 15 = 150
\n" ); document.write( "solve for r to get r = 150 / 75 = 2.
\n" ); document.write( "the rate that each sheep eats grass is 2 kilograms per day.
\n" ); document.write( "when n = 9 and r = 2 and q = 90 kilograms, the formula becomes:
\n" ); document.write( "9 * 2 * t = 90
\n" ); document.write( "solve for t to get t = 90 / 18 = 5
\n" ); document.write( "9 sheep will eat 90 kilograms in 5 days.\r
