At a concert, the ratio of adults to children is 3:8.
\n" ); document.write( "\"a%2Fc\" = \"3%2F8\"
\n" ); document.write( ":
\n" ); document.write( " The ratio of girls to boys is 3:4.
\n" ); document.write( "\"g%2Fb\" = \"3%2F4\"
\n" ); document.write( "we know
\n" ); document.write( "c = g + b
\n" ); document.write( ":
\n" ); document.write( "Choose a total, the Least common multiple of (3+8),11; and (3+4),7
\n" ); document.write( "LCM = 77
\n" ); document.write( "then
\n" ); document.write( "a + c = 77
\n" ); document.write( "\"a%2Fc\" = \"3%2F8\" therefore dividing 77 by 11 is 7, so we have:
\n" ); document.write( "3*7 = 21 adults
\n" ); document.write( " and
\n" ); document.write( "8*7 = 56 children
\n" ); document.write( "then we know
\n" ); document.write( "g + b = 56
\n" ); document.write( "\"g%2Fb\" = \"3%2F4\" therefore dividing 56 by 7 is 8, so we have
\n" ); document.write( "3*8 = 24 girls
\n" ); document.write( "4*8 = 32 boys
\n" ); document.write( ":
\n" ); document.write( "therefore adults to girls:
\n" ); document.write( "\"a%2Fg\" = \"21%2F24\" reduces to \"7%2F8\" is the ratio of adults to girls
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check out by adding; adults, boys, and girls. 21 + 24 + 32 = 77 total\r
