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.
still dont undertand how to do it can someone explain better how to solve this problem
I think you may want to look at Mertsj's answer.. it is pretty detailed
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
