so you know that we can do 50 - 8 which equals 42.
42 is not the answer because there was a little more than 8 feet used
So if you have 50 pizzas which are cut into 6 slices each and you at 8 of them you have 42 pizzas left. But if you eat 5 slices you have 41 and 1 slice left which is equal to 41 1/6
Hope this helps!!!
