Answer:
C
Explanation:
The first number on the mechanic's list is the one that is most negative. The negative numbers on the list are ...
-3/16, -1/4, -1/16
These are easier to compare if they have a common denominator:
-1/4 = -4/16
So, the numbers are ...
-3/16, -4/16, -1/16
The one that is most negative is -4/16 = -1/4. Only one answer choice has this listed first. (No further work is necessary.)
