  1. Basic Math & Measurement For Graphic Communications

  2. Measurement • Each line= 1/16” • 2 lines= 1/8” • 4 lines= 1/4” • 8 lines= 1/2” • 16 lines= 1 inch

  3. Understanding the Ruler • On your worksheet, answer the questions about the ruler.

  4. Answers to Measurement • 2 8. 12 • 4 9. 14 • 8 • 16 • 2 • 4 • 8

  5. Answers to Measurement • 5/8 H. 3 11/16 • 1 1/16 I. 3 7/8 • 1 1/2 J. 4 • 2 11/16 K. 4 1/16 • 2 15/16 • 3 1/4 • 3 7/16

  6. Answers to measurement • 1 1/4 8. 2 3/8 • 2 1/8 9. 2 3/8 • 3/4 10. 3 5/8 • 4 1/16 • 1 1/16 • 15/16 • 6

  7. Fractions • Each number in fractions is identified by a name

  8. Fractions: Addition • Remember to add fractions, the denominator must be the same • Example:

  9. Fractions: Addition • Study this example • Since the 2 and 3 are not alike you must select a denominator that both 2 and 3 will divide into evenly.

  10. Fractions: Addition • In this case the common denominator is 6.

  11. Fractions: Subtraction • The same addition rules apply. • The only difference is you subtract instead of add.

  12. Fractions: Worksheet • On your worksheet, complete the fractions section.

  13. Fractions Answers • 7/6 = 1 1/6 1. .75 8. .05 • 4/4 = 1 2. .125 9. .85 • 6 3/16 3. .0625 10. .15 • 1/16 4. 1.75 • 2/4 = 1/2 5. 11.25 • 3 3/16 6. 65% 7. 175%

  14. Enlargements & Reductions • Formula for enlargements/reductions if the size and reproduction size are known. This formula is used to find the needed reproduction %.

  15. Enlargements & Reductions • Use this formula to find the new size if the percentage & original size are known.

  16. Enlargements & Reductions • On your worksheet, complete the enlargement & reductions section.

  17. Answers toEnlargements & Reductions • 50% 1. 9” 1. 44% • 266% 2. 5.7375” 84 • 18.3% 3. 9.2” 2. 75% • 33.3% 4. 4.33125” 70%

  18. Type Measurements • 12 points= 1 pica • 72 points= 6 picas • 72 points= 1 inch • 6 picas= 1 inch

  19. Type Measurement • Example: 6 inches = ? Picas 6 x 6= 36 picas Note: 6 picas = 1 inch. So, you multiply 6 inches x 6 picas

  20. Type Measure • Complete the type measurement section on you worksheet

  21. Type Measurement Answers • 144 • 18 • 5.5 • 7 • 2, 3.5

  22. Liquid Measurement • 8 fluid ounces = 1 cup • 2 cups = 1 pint • 2 pints = 1 quart • 4 quarts = 1 gallon • 1 liter = .26 gallons

  23. Liquid Measurement • Example: • A press helper has been asked to mix a special fountain solution for the press. The directions call for using 3 cups of alcohol, 8 fluid ounces of a special concentrate, and 3 quarts of water. What quantity will there be when mixed?

  24. Liquid Measurement • Solution to example 3 cups = 24 fl. Oz. 3 qts. = 96 fl. Oz. 24 fl. Oz. + 8 fl. Oz. + 96 fl. Oz.= 128 fl. Oz. or 1 gallon

  25. Liquid Measurement • Complete the liquid measurement section of your worksheet

  26. Liquid Measurement Answers • Liquid Measurement 1 1. 2 full cube containers (25 liters = 25 x .2642 = 6.605 gallon capacity, 2 full cube containers is 5 gallons) 2. 1.4346 gallons (13 x .2642 = 3.4346 gallons ﾐ 2 gallons = 1.4346 gallons)

  27. Liquid Measurement Answers 2 • Cup • 2 • 8 • 4,16

  28. Estimating • Estimating combines all of the basic math skills. • Use these skills to solve the problems on your work sheet.

  29. Estimating Answers • $ 613.50 • $1,400.00 • $10.00
