Quiz tematico 1: Fractions, decimals and the tape measure

  1. Domanda 1 di 15

    A tape measure is marked in sixteenths of an inch. How many sixteenths are in 3/4 in?
    Mostra la risposta

    Risposta: B. 12

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

  2. Domanda 2 di 15

    You measure a gap of 10/16 in. What is this fraction in lowest terms?
    Mostra la risposta

    Risposta: 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. Domanda 3 di 15

    What is 7/8 in as a decimal?
    Mostra la risposta

    Risposta: 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. Domanda 4 di 15

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

    Risposta: 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. Domanda 5 di 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?
    Mostra la risposta

    Risposta: D. 60 3/8 in

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

  6. Domanda 6 di 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?
    Mostra la risposta

    Risposta: 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. Domanda 7 di 15

    You stack 6 spacer blocks. Each block is 1 5/8 in thick. How tall is the stack?
    Mostra la risposta

    Risposta: 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. Domanda 8 di 15

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

    Risposta: 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. Domanda 9 di 15

    A plan gives a length of 12.75 ft. What is this in feet and inches?
    Mostra la risposta

    Risposta: 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. Domanda 10 di 15

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

    Risposta: D. 1.047 m

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

  11. Domanda 11 di 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?
    Mostra la risposta

    Risposta: 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. Domanda 12 di 15

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

    Risposta: 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. Domanda 13 di 15

    A drawing gives a thickness of 0.3125 in. What fraction of an inch is this?
    Mostra la risposta

    Risposta: B. 5/16 in

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

  14. Domanda 14 di 15

    Which of these drill bit sizes is the largest?
    Mostra la risposta

    Risposta: 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. Domanda 15 di 15

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

    Risposta: 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.

Cosa sapere prima del test

  • 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.

Domande frequenti

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.

L’attestato è accreditato o riconosciuto ufficialmente?

No. È un attestato di completamento privato, solo per le tue conoscenze. Non è riconosciuto, accreditato né approvato da alcun governo, ente di rilascio delle licenze, autorità di regolamentazione o istituto di istruzione e non sostituisce alcuna licenza, certificazione o formazione richiesta dalla legge.
