Directions: Using the digits 1 to 9, at most one time each, place a digit in each box so that the three fractions have a product as close to 1 as possible.
Hint
What must be true about the numerator and denominator for the final result to be equal to 1?
Answer
There are many answers but all of them will either be 36/36 or 72/72 when multiplied out. For example, 6/9 x 4/8 x 3/1 = 72/72 = 1

we are in fifth grade and we found another solution. Our solution was: (1/3 x 9/4) x 8/6 = 72/72 or 1.
You could also do 2/6+12/4=24/24=1
that is addition her is multipilcation
