Fishing lines can have a diameter as small as 2x10 to the power of -2 inch and as large as 6x10 to the power of -2 inch. . How many times larger is the thick line compared to the thin

Answer 1

You can solve this with or without scientific notation. Let's first do it with scientific notation.

the ratio of thick line to thin is:

6 x 10^-2 : 2 x 10^-2 now multiply both sides by 10² giving

6 : 2 or 3 : 1 So the thick line is 3 times thicker than the thin line

Without scientific notation, first convert the ratio to decimal notation, and let's use fractions this time

.06/.02 = 6/2 = 3/1
