Question

Some wrench sets come in metric units and others come in standard units. A chart compares the measurements of a metric set of wrenches with the equivalent measurements in inches.
 

 

Metric to Inches Conversion
Metric  wrench size in millimeters	Equivalent size in inches
4	0.1572
5	0.1965
6	0.2358
7	0.2751
8	0.3144
9	0.3537

If Caleb only has metric wrenches and needs a  inch wrench, how could he use the chart to choose the best fit?

Caleb should use the 5 millimeter wrench because that would be closest to  inches since they both have 5.

Caleb should divide 5 by 16 to get a decimal of 0.3125. Then, he should try the 7 millimeter and 8 millimeter wrenches because 0.2751 < 0.3125 < 0.3144.

Caleb should divide 16 by 5 to get a decimal of 3.2. Then, he should try the 8 millimeter and 9 millimeter wrenches because 0.3144 < 3.2 < 0.3537.

Caleb should use a 20 millimeter wrench because 4 millimeters  so .

Answer 1

5/16=0.3125; so 0.3144 is the nearest which is size 8. Answer 2 is the best.

Answer 2

I'm pretty sure it's C
