  1. Industrial Skills Math and Measurement Review: Skill Assessment Quiz

  2. Add 666+434+204+989= 666 434 204 989 2,293 Subtract 847 from 9321= 9,321 - 847 8,474 Multiply 784 by 13 = 784 Χ 13 2352 784 10,192 Divide 3172 by 152 = 21 20.86 152 3172.00 304 132.0 1216 1040 912 120 Whole Numbers

  3. Add 3/8 + 5/8 + 7/8 = 3/8 5/8 7/8 15/8 = 1 7/8 (Common Denominators) Add 10 9/16 + 4 1/8 + 2 1/2 + 3 = 10 9/16 = 9/16 4 1/8 = 2/16 2 1/2 = 8/16 3 19 19/16 = 20 3/16 (Uncommon Denominators) Fractions: Addition

  4. Subtract 17/8from 2 3/8 = 2 3/8 = 1 11/8 - 1 7/8 = 1 7/8 0 4/8 = 1/2 (Common Denominators) Subtract 713/16from 101/4 = 10 1/4 = 9 20/16 - 7 13/16 = 7 13/16 2 7/16 (Uncommon Denominators) Fractions: Subtraction

  5. Multiply 7/8 by 3/4 = 7/8 x 3/4 = 21/32 (Numerator x Numerator) (Denominator x Denominator) Multiply 11/2 x 11/2 x 11/2 = 3/2 x 3/2 = 9/4 x 3/2 = 27/8 = 3 3/8 Or 3 x 3 x 3 27 = = 3 3/8 2 x 2 x 2 8 Fractions: Multiplication

  6. 21 ÷ 1/4 = (invert the divisor and multiply) 21/1 x 4/1 = 84/1 = 84 1/4 ÷ 21 = (invert the divisor and multiply) 1/4 x 1/21 = 1/84 3 1/16÷ 1/4 = (invert the divisor and multiply) 3 1/16 = 49/16therefore 49/16 x 4/1 = 196/16 (12 x 16 = 192) = 12 4/16 = 12 1/4 Or 3÷ 1/4 = 3/1 x 4/1 = 12/1 1/16 ÷ 1/4 = 1/16 x 4/1 = 4/16 Therefore 12/1 + 4/16 = 12 4/16 = 12 1/4 Fractions: Division

  7. Decimals: Addition & Subtraction • Add 244.05 + 43.1 + 7.982 + 22 = • 244.05 43.1 7.982 (When adding numbers, align the decimals) 22.000 317.132 • Subtract 783.21 from 897.37 = • 897.37 - 783.21 (When subtracting numbers, align the decimals) 114.16

  8. Multiply 1125 x 1.5 = 1125 x 1.5 5625 1125 1687.5 Multiply 1.321 x 2.51 = 1.321 x 2.51 1321 6605 2642 3.31571 Decimals: Multiplication

  9. Divide 326.16 by 72 = 4.53 72 326.16 288 381 360 216 216 Divide 39.375 by 4.375 = 9. 4.375 . 39.375. Divide .133 by .7 = .19 .7. .1.33 7 63 63 Decimals: Division

  10. Convert 3/8 inch to a decimal = .375 inches 3 ÷ 8 = .375 Or 1/2” = .50” 1/4” = .25” 1/8” = .125” 1/16” = .0625” So .25” + .125” = .375” Convert 1 3/4 inch to a decimal = 1.75 inches 3 ÷ 4 = .75therefore1 + .75 = 1.75 Or 1/2” = .50” 1/4” = .25” 1/8” = .125” So 1” + .50” + .25” = 1.75” Conversions: Fractions to Decimals

  11. Convert 1.125 inches to a common fraction = 1.125” = 1 125/1000” Or 1/2” = .50” 1/4” = .25” 1/8” = .125” 1/16” = .0625” So 1” + .125” = 1 1/8” Convert 2.625 inches to a common fraction = 2.625” = 2 625/1000” Or 1/2” = .50” 1/4” = .25” 1/8” = .125” 1/16” = .0625” So 2” + .50” + .125” = 2 5/8” Conversions: Decimals to Fractions

  12. Estimating Measurements: • Draw a line in the space below that you would estimate to be approximately 1 inch long. • Draw a line in the space below that you would estimate to be approximately 50 millimeters long
