Exercises | Reading | Observation |
---|---|---|

1 | 3/8″ | The numeral strokes are those of the whole inches, between two of them, there is a slightly shorter stroke, which is half 1/2″, whose half is 1/4″; Its half is the eighth of of an inch, 3/8″. |

2 | 1″ | |

3 | 13/16″ | The object is 1/16″ (see, the inch was divided into 32 parts, so each one is 1/32″.) 2 x 1/32″ = 2/32″, simplifying, = 1/16″) greater than 3/4″. So, 3/4″ = 6/8″ = 12/16″. 12/16″ + 1/16″ = 13/16. |

4 | 13/32″ | Note that the number next to where the zero should be indicates the smallest division of this part of the scale and a 32th of an inch. Count each space between the marks to the left of the lined one and you will see that they are 13 (13/32). Note that the trait on the left is 3/8 (exercise 1) remember that 3/8 = 6/16 = 12/32 which adding 1/32 results in 13/32 “ |

5 | 2.1/4″ | |

6 | 1.1/2″ | |

7 | 1/4″ | The object was positioned at the 1/4 inch mark and went up to the 1/2 (2/4) inch mark. |

8 | 9/32″ | See that the object was positioned 1/32″ left of the 1/4″ mark and went until the 1/2″ mark, (1/4 = 8/32) 8/32 + 1/32 = 9/32″ |

9 | 1.7/8″ | |

10 | 1/32″ |
