Question

four inches of a (somewhat magnified ) ruler is shown. use the ruler to give the length of the gray bar, to the nearest sixteenth of an in. write answer as a mixed #. (simplify as much as possible)

Answer 1

We have the following:

We have that 4 is equal to 64/16

`(4\cdot16)/(1\cdot16)=(64)/(16)`

Thefore:

The bar is found in 2 and 15 more lines, each line is 1/16

`(2\cdot16)/(1\cdot16)+(15)/(16)=(32)/(16)+(15)/(16)=(47)/(16)=2(15)/(16)`
