Question

The roots of 6 corn plants had depths of -3.54 feet? /2 4/5 feet, /3.86 feet, -3 2/5 feet. How many corn plants had roots between 3 and 4 feet deep?

Answer 1

Since roots go down into the ground, the answers must be negative. That eliminates both 2 4/5 deep and 3.86. You could look at a number line if your unsure, but -3.54 is between 3 and 4, as is -3 2/5.
