Prueba temática 1: Fractions, decimals and the tape measure

  1. Pregunta 1 de 15

    A tape measure is marked in sixteenths of an inch. How many sixteenths are in 3/4 in?
    Ver respuesta

    Respuesta: B. 12

    3/4 = 12/16, because you multiply the top and bottom by 4. So 3/4 in is 12 sixteenth marks.

  2. Pregunta 2 de 15

    You measure a gap of 10/16 in. What is this fraction in lowest terms?
    Ver respuesta

    Respuesta: C. 5/8 in

    Divide the top and the bottom by the same number. 10 ÷ 2 = 5 and 16 ÷ 2 = 8, so 10/16 = 5/8.

  3. Pregunta 3 de 15

    What is 7/8 in as a decimal?
    Ver respuesta

    Respuesta: B. 0.875 in

    Divide the top by the bottom: 7 ÷ 8 = 0.875. (0.625 is 5/8 and 0.75 is 3/4.)

  4. Pregunta 4 de 15

    A carpenter adds two measurements: 2 3/8 in + 1 3/4 in. What is the total?
    Ver respuesta

    Respuesta: D. 4 1/8 in

    Change 3/4 to 6/8, then add: 3/8 + 6/8 = 9/8 = 1 1/8. Add the whole numbers (2 + 1 = 3) and the carried 1 to get 4 1/8 in.

  5. Pregunta 5 de 15

    A board is 96 in long. You cut off a piece 35 5/8 in long. Ignoring the saw cut, how long is the piece that is left?
    Ver respuesta

    Respuesta: D. 60 3/8 in

    Borrow 1 inch: 96 = 95 8/8. Then 95 8/8 − 35 5/8 = 60 3/8 in.

  6. Pregunta 6 de 15

    You cut 4 pieces, each 18 1/4 in long, from one board. Each cut removes 1/8 in of wood (the kerf), and you make 4 cuts. How much of the board do you use?
    Ver respuesta

    Respuesta: C. 73 1/2 in

    Pieces: 4 × 18 1/4 = 73 in. Kerf: 4 × 1/8 = 1/2 in. Total 73 + 1/2 = 73 1/2 in.

  7. Pregunta 7 de 15

    You stack 6 spacer blocks. Each block is 1 5/8 in thick. How tall is the stack?
    Ver respuesta

    Respuesta: D. 9 3/4 in

    Change 1 5/8 to an improper fraction: 13/8. Then 6 × 13/8 = 78/8 = 9 6/8 = 9 3/4 in.

  8. Pregunta 8 de 15

    You must divide 72 in into 5 equal spaces. What is each space, to the nearest 1/16 in?
    Ver respuesta

    Respuesta: B. 14 3/8 in

    72 ÷ 5 = 14.4 in. 0.4 × 16 = 6.4 sixteenths, which rounds to 6/16 = 3/8. So each space is about 14 3/8 in.

  9. Pregunta 9 de 15

    A plan gives a length of 12.75 ft. What is this in feet and inches?
    Ver respuesta

    Respuesta: D. 12 ft 9 in

    Only the decimal part changes: 0.75 ft × 12 = 9 in. So 12.75 ft = 12 ft 9 in, not 12 ft 7.5 in.

  10. Pregunta 10 de 15

    A metric tape reads 1 metre, 4 centimetres and 7 millimetres. What is this length in metres?
    Ver respuesta

    Respuesta: D. 1.047 m

    4 cm = 0.04 m and 7 mm = 0.007 m. 1 + 0.04 + 0.007 = 1.047 m.

  11. Pregunta 11 de 15

    On a tape marked in sixteenths, the end of a part lines up 5 small marks past the 2-inch line. How long is the part?
    Ver respuesta

    Respuesta: B. 2 5/16 in

    Each small mark is 1/16 in, so 5 marks = 5/16 in. The length is 2 5/16 in.

  12. Pregunta 12 de 15

    You join three pieces of pipe: 1.25 m, 760 mm and 0.6 m. What is the total length?
    Ver respuesta

    Respuesta: D. 2.61 m

    Put everything in metres first: 760 mm = 0.76 m. Then 1.25 + 0.76 + 0.6 = 2.61 m.

  13. Pregunta 13 de 15

    A drawing gives a thickness of 0.3125 in. What fraction of an inch is this?
    Ver respuesta

    Respuesta: B. 5/16 in

    Multiply by 16: 0.3125 × 16 = 5. So 0.3125 in = 5/16 in.

  14. Pregunta 14 de 15

    Which of these drill bit sizes is the largest?
    Ver respuesta

    Respuesta: B. 5/8 in

    Change each to a decimal: 5/8 = 0.625, 19/32 = 0.594, 0.6 and 9/16 = 0.5625. 0.625 is the largest.

  15. Pregunta 15 de 15

    A board is 47 3/8 in long. Where do you mark its centre, measured from one end?
    Ver respuesta

    Respuesta: B. 23 11/16 in

    Half of 47 is 23 1/2 = 23 8/16, and half of 3/8 (6/16) is 3/16. 23 8/16 + 3/16 = 23 11/16 in.

Qué debes saber antes del examen

  • The Government of Canada's Skills for Success model defines numeracy as the ability to find, understand, use and report mathematical information in words, numbers, symbols and graphics.
  • Numeracy is one of nine Skills for Success. The model describes five numeracy proficiency levels; at the highest level, tasks have several steps and numbers may need to be derived or estimated.
  • Under the Weights and Measures Act, all units of measurement used in Canada are based on the International System of Units (SI).
  • The Act defines the yard as exactly 0.9144 metre and the inch as 1/36 of a yard, so 1 inch is exactly 25.4 mm.
  • The Act defines the Canadian gallon as 0.00454609 cubic metre (4.54609 L) and the pound as 0.45359237 kilogram.
  • Red Seal exam questions are multiple choice with four choices and one correct answer, and the pass mark is 70%.
  • The Red Seal exam guide advises candidates to know the math concepts used in their trade and to estimate the answer to a calculation question first.
  • The Canada Revenue Agency lists the GST rate in Alberta as 5%, with no provincial sales tax.

Preguntas frecuentes

What is the Certificate of Completion, and what is it not?

It shows that you finished this course and scored at least 80% on the final assessment. It is not an accredited qualification, a Red Seal or apprenticeship credential, or a government, employer or vendor certification.

Will this course prepare me for the Red Seal exam?

It practises the general math that many trades use, which can help. The Red Seal exam also tests the full knowledge of your trade, so study your trade's occupational standard and official Red Seal preparation materials too.

Does the course use metric or imperial units?

Both, because Canadian job sites use both. Lesson 2 shows how to convert between them using the exact definitions in the Weights and Measures Act.

Can I use a calculator?

Yes. Most questions are easier with a calculator, and the trigonometry questions need one set to degrees. Estimate the answer first so you can spot a slip.

How does the final assessment work?

It has 35 questions drawn at random from the course question bank, with a 35-minute time limit. You need 80% to pass, and each attempt gives a new mix of questions.

¿El certificado está acreditado o reconocido oficialmente?

No. Es un certificado de finalización privado, solo para tus conocimientos. No está reconocido, acreditado ni aprobado por ningún gobierno, organismo de licencias, regulador ni institución educativa, y no sustituye ninguna licencia, certificación ni formación exigida por la ley.
