Question

Dr.hong prescribed 0.019 liter morre medicine than Dr.T . Dr.E prescibed 0.02 less than Dr.hong who prescibed the most medicine who prescribed the least

Answer 1

Dr. Hong prescribed the most. She/He prescribed more than both Dr. T and Dr. E. We know this without doing any calculations.

Now, notice that 0.02 is GREATER than 0.019. So, the difference between Dr. Hong and Dr. E is GREATER than the difference between Dr. Hong and Dr. T. That is, Dr. E prescribed the least.

This means Dr. T was in the middle.
