Paco has 2 1/3 feet of rope. if he cuts the rope into pieces that are each 1/2 foot long, there will be 1/3 foot of rope left over. how many 1/2 foot pieces will he have?

He will have 4 1/2 foot pieces of rope
To calculate this, we need to divide 2 by 1/2.
To make this simpler, say you have 2 pizzas and cut each pizza in half. How much halfs will you have? You will have four halfs. Same with the rope. You will have 4G pieces of rope. I attached an image that I hope will help :)

If i think this is what your asking, he should look at the grams or pounds/ounces and compare the to their cost then max can identify which one is proportional and which is not ( i think xd)
