Hello there! I can help you! The parts between each inch are measured in sixteenths. Each line equals 1/16 of an inch. The line 1/2 way between an inch equals 8/16. Let's start off with the first one. The measurement of the first ruler is 11 5/16 inches, because the arrow points to a line 5 units away from 11. If you solve these correctly, here are your answers:
1. 11 5/16
2. 2 1/2
3. 7/16
4. 11/16
5. 11 6/16 or 11 3/8 in simplest form
