\n" ); document.write( "Peter had 3/8 as many marbles as Simon. After Simon misplaced 3/4 of his marbles, Peter had 120 more marbles than Simon. How many marbles did Peter have?
\n" ); document.write( "
With Peter (P) having \"3%2F8\" of marbles that Simon (S) has, Simon (S) would have: \"matrix%281%2C4%2C+%288%2F3%29P%2C+or%2C+8P%2F3%2C+marbles%29\"
\n" );
document.write( "Since Simon misplaced \"3%2F4\" of his marbles, he would have: \"matrix%281%2C3%2C+%281%2F4%29+%2A+%288P%2F3%29%2C+or%2C+2P%2F3%29\" left
\n" );
document.write( "With Peter (P) now having 120 more marbles than Simon, we get: \"matrix%281%2C3%2C+P%2C+%22=%22%2C+2P%2F3+%2B+120%29\"
\n" );
document.write( "3P = 2P + 360 ------ Multiplying by LCD, 3
\n" );
document.write( "Original number of marbles Peter had, or \"highlight_green%28matrix%281%2C3%2C+P%2C+%22=%22%2C+360%29%29\" \n" );
document.write( "
\n" );
