Directions: Using the digits 1 to 9 at most one time each, place a digit in each box to make a product that’s as close to 4/11 as possible.
However Mr. Ries’ fifth graders found an even better answer. They got 6/8 x 2/4 which gives a product that is a closer to 4/11. There will be equivalent alternative answers such as 3/4 x 1/2 or 6/8 x 1/2.
