There are 152 students in 5th grade. 1/11 of the boys and 5 girls join a science club. In the rest of the students, boys and girls are equal. How many boys vs girls are in 5th grade?
\n" ); document.write( "

Let number of boys be B
\n" );
document.write( "Then number of girls = 152  -  B
\n" );
document.write( "If  of the boys joined the science club, then number of boys left = 
\n" );
document.write( "If 5 girls joined the science club, then number of girls left = 152 - B - 5 = 147 - B
\n" );
document.write( "Since remaining sets are equal, we can then say that: 
\n" );
document.write( "10B + 11B = 11(147) ------ Multiplying by LCD, 11 
\n" );
document.write( "21B = 11(147)
\n" );
document.write( "Number of boys in the 5th grade, or 
\n" );
document.write( "Number of girls? You should be able to find this!
\n" );
document.write( "N.B. You DON'T need to use all those variables that the other people used. It's UNNECESSARY, makes the problem more complicated, and can possibly lead to many mistakes! \n" );
