In this example, there are 2 unhealthy barnacles out of a total of 5 barnacles all together, so the fractions is 2/5.


Search Grid- Fraction: A fraction always has a number on the bottom (the denominator) that tells how many pieces there are in total, and a number on top (the numerator) that tells how many are the thing you're measuring this time.
