Question
Of the following, which is least?
- 0.03/0.00071
- 0.03/0.0071
- 0.03/0.071
- 0.03/0.71
- 0.03/7.1
Topics: calculations, decimals, comparisons
Solution
Step 1
We apply ("Chain Rule for Inequalities") to note that the denominators increase in the following order
0.00071<0.0071<0.071<0.71<7.1
Step 2
We observe that with the same positive numerator, a larger denominator gives a smaller fraction
0.03/0.00071>0.03/0.0071>0.03/0.071>0.03/0.71>0.03/7.1
Step 3
We see that the fraction with the largest denominator is the smallest
0.03/7.1 (Option E)
Answer
The least value is 0.03/7.1, which is option E
