Donald's score of 5/8 is equal to 0.625. Gino scored 3/5 which is 0.6. Sierra's score of 4/5 equals 0.8. Karen's score is already given, and 0.88 is greater than 0.6. None of the students obtained lower than a 0.6. However, if at least does not include scores equal to 0.6, and only scores greater than 0.6, then Gino possibly failed this math test. However, if a passing score is equal to or greater than 0.6, then all four students passed the test.
