Question

B. As part of the assignment, you need to make a ratio table using the scale factor 0.5 nm

to 10 inches. A partially completed ratio table is shown. What value can be placed
where the question marks (?) are? Show all your work.
Nanometers Inches
? 5
0.5 10
1 20
3 ?

Answer 1

Answer: The ratio between the units of measurement of nanometers and inches is 0.5 nm to 10 inches. This means that for every 0.5 nanometers, the equivalent measurement in inches is 10 inches.

We can use this ratio to find the conversion of other values from nanometers to inches as well.

We know that 1 nm = 20 inches, we can multiply the value 1 by 20 to get 20 inches

So 3 nm will be 3 * 20 = 60 inches

so, the value that can be placed in the ratio table where the question marks (?) are would be 1 nm = 20 inches

and 3 nm = 60 inches.
