  1. Read a tape measure

  2. Measuring tools • Tape measure • Ruler • Yard stick • Folding ruler • Measuring wheel • Scale ruler

  3. QUESTIONS • Who wants to maximize their proficiency? • Which tool do you think is a primary measuring tool in the Automotive field? • Today you are going to learn how to use a ruler to make proper measurements in whole and fractional units.

  4. FRACTIONS OF AN INCH HALF INCH INCREMENTS http://www.rickyspears.com/rulergame/

  5. FRACTIONS OF AN INCH One-quarter inch measures

  6. FRACTIONS OF AN INCH One-eighth of an inch

  7. FRACTIONS OF AN INCH Two-sixteenths of an inch or One-eighth of an inch

  8. FRACTIONS OF AN INCH Three-sixteenths of an inch

  9. FRACTIONS OF AN INCH Four-sixteenths of an inch or Two-eighths of an inch or One-fourth of an inch

  10. FRACTIONS OF AN INCH Five-sixteenths of an inch

  11. FRACTIONS OF AN INCH Six-sixteenths of an inch or Three –eights of an inch

  12. FRACTIONS OF AN INCH Seven-sixteenths of an inch

  13. FRACTIONS OF AN INCH Eight-sixteenths of an inch or Four-eighths of an inch or Two-fourths of an inch or One-half of an inch

  14. FRACTIONS OF AN INCH Nine-sixteenths of an inch

  15. FRACTIONS OF AN INCH Ten-sixteenths of an inch or Five-eighths of an inch

  16. FRACTIONS OF AN INCH Eleventh-sixteenths of an inch

  17. FRACTIONS OF AN INCH Twelve-sixteenths of an inch or Six-eighths of an inch or Three-fourths of an inch

  18. FRACTIONS OF AN INCH Thirteen-sixteenths of an inch

  19. FRACTIONS OF AN INCH Fourteen-sixteenths of an inch or Seven-eighths of an inch

  20. FRACTIONS OF AN INCH Fifteen-sixteenths of an inch

  21. FRACTIONS OF AN INCH Sixteen-sixteenths of an inch or One inch

  22. ADDING MEASURES

  23. FRACTION RULES RULES 1. To add fractions you must have a common denominator 2. Reduce fractions

  24. COMMON DENOMINATOR How do you get a common denominator? 8 can be the common denominator when the fractions are in fourths or eighths. 16can be the common denominator for all rulers marked in 16ths. Use 32as the common denominator when the ruler is marked in 32nds.

  25. COMMON DENOMINATOR Multiply top and bottom by the same value to change the denominator correctly.

  26. ADDING MEASURES • Get the common denominator • Rewrite the fractions

  27. ADDING MEASURES • Get the common denominator • Rewrite the fractions • Add the numerators • Carry the denominator forward

  28. ADDING MEASURES • Get the common denominator • Rewrite the fractions • Add the numerators • Carry the denominator forward • Reduce the answer

  29. ADDING MEASURESwith WHOLE NUMBERS • Add the whole numbers (like always) • Get the common denominator • Rewrite the fractions • Add the numerators • Carry the denominator forward • Reduce the answer

  32. REMEMBERCOMMON DENOMINATORADDING & SUBTRACTING How do you get a common denominator? 8 can be the common denominator when the fractions are in fourths or eighths. 16can be the common denominator for all rulers marked in 16ths. Use 32as the common denominator when the ruler is marked in 32nds.

  33. COMMON DENOMINATOR Multiply top and bottom by the same value to change the denominator correctly.

  34. SUBTRACTING MEASURES • Get the common denominator • Rewrite the fractions

  35. SUBTRACTING MEASURES • Get the common denominator • Rewrite the fractions • Subtract the numerators • Carry the denominator forward

  36. SUBTRACTING MEASURES • Get the common denominator • Rewrite the fractions • Subtract the numerators • Carry the denominator forward • Reduce the answer

  37. SUBTRACTING MEASURESwith WHOLE NUMBERS • Subtract the whole numbers (like always) • Get the common denominator • Rewrite the fractions • Subtract the numerators • Carry the denominator forward • Reduce, if necessary

  38. SUBTRACTING MEASURES

  39. SUBTRACTING MEASURES

  40. SUBTRACTING MEASURES

  41. MULTIPLYING MEASURES • One-half of 1 inch means or of 1 inch “of is another way to say times”

  42. MULTIPLYING MEASURES Two times one-half is adding one-half two times. 2 X  = 1 +  =1
