Question

One inch of a (greatly magnified) ruler is shown. Use it to give the length of the gray bar to the nearest sixteenth of an inch. Simplify your fractional answer as much as possible!

Answer 1

Answer

Length of the gray = (12/16) inch = (3/4) inch

Explanation

Each small line demarcating each small region between 0 and 1 represents one-sixteenth of an inch.

So, there 16 such small regions between 0 and 1.

And the region indicated goes from 0 and covers 12 of the 16 small regions.

So, the measure indicated is

(12/16)

To reduce to the smallest fraction, we divide numerator and denominator by 4

(12/16) = (3/4)

Hope this Helps!!!
