Answer: 2 1/2 inches; 9 lines
Explanation:
If one has a line that is 2.5 inches in decimal, this in fraction form will be written as:
= 2.5 inches = 2 5/10 inches.
When we reduce 5/10 to its lowest term, this will be 1/2. Therefore 2.5 inches = 2 1/2 inches.
Since each mark on a ruler is 1/16, therefore 9/16 will be (9/16 ÷ 1/16) = (9/16 × 16/1) = 9 lines
