Final Arrangement

Question: At this stage in the game, list some fraction cards you could and could not use if you drew them now, and record your reasoning. How would you communicate your reasoning to another person?

Show Answer
Our Answer:
You can't use 1/8, 3/8, 5/8, and 7/8. You can use all halves, thirds, fourths, fifths, sixths, and tenths. You can also use all eighths with even numerators (2/8, 4/8, 6/8, 8/8), because these can be used on a single track or can be converted to sums of equivalent fractions and then used on two or more tracks. The other eighths cannot be converted to a sum of equivalent fractions that could be used on one of the available tracks, as any such sum would leave at least 1/8 remaining, and the eighths track is already full.
