    2 oranges = 3 pears so 1 pear = 2/3 orange 4 pears = 3 apples so 1 pear = 3/4 apple and therefore 2/3 orange = 3/4 apple Multiply both sides by 3/2 and get 1 orange = 9/8 apples Now multiply by 72 to get 72 oranges. 72 oranges = 72(9/8) apples = 81 apples.

    3 apples = 4 pears 3pears = 2 oranges x apples = 72 oranges Solve for x It's a system of equations, solve by elimination, or by substition. What part is confusing you castro? :D
