Strategies

This exercise is easy to get accuracy badges because a calculator can be used to compare the fractions in decimal form which is much easier.Speed badges are hard because there are a lot of tiles to manipulate on some problems and there is often one or two non-obvious comparisons.

  1. Most of the fractions can be quickly compared to standard fractions with the number 1 in their numerator.
  2. Sometimes there is a hard fraction to work with, in which case the cross multiply comparison technique works well if users want to be honest, or a calculator can also so the trick.
  3. Only need to get three correct in a row to move to next level.
