Jeff is playing a new video game the goal is to explore a cave with many levels and collect gold coins in order to get through a door to the next level you must master a secret code jeff's video character has 4 pockets on his jacket the top left pocket is marked with 3/4 the top right is marked 5/15 the lower left pocket is 8 /12 and the lower right pocket is 9/12 Above the cave door at each level is a number card to open the door he must take the number card form the door and put it in the correct pocket if he puts it in the wrong pocket he loses one of his 3 lives number are 6/8 4/8 6/9 16/32 21/28 12/18 6/12 6/18

I marked the pockets in red in the picture. The first goes in the bottom right, the second goes in the top left. And so on.

Explanation:
I think the easiest way is to simplify them all, so that you can find which ones are equal! I marked the pockets in red on each door. But for example, 3/6 is equal to 1/2 because if you multiply 1/2 x 3/3 you get (1 x 3)/ (2 x 3) or 3/6. So the goal is to find a number you can divide the fraction by. You can see if it’s all the way simplified you can no longer divide the top and bottom by the same number. In the second door, you could start by dividing by 2: 4/8 divided by 2/2 is 2/4. But now we can divide by 2 again: 2/4 divided by 2/2 is 1/2. And 1/2 matches one of our pockets, the top left one!
