Themaquiz 1: Fractions, decimals and the tape measure

  1. Vraag 1 van 15

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

    Antwoord: B. 12

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

  2. Vraag 2 van 15

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

    Antwoord: 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. Vraag 3 van 15

    What is 7/8 in as a decimal?
    Toon antwoord

    Antwoord: 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. Vraag 4 van 15

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

    Antwoord: 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. Vraag 5 van 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?
    Toon antwoord

    Antwoord: D. 60 3/8 in

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

  6. Vraag 6 van 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?
    Toon antwoord

    Antwoord: 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. Vraag 7 van 15

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

    Antwoord: 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. Vraag 8 van 15

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

    Antwoord: 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. Vraag 9 van 15

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

    Antwoord: 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. Vraag 10 van 15

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

    Antwoord: D. 1.047 m

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

  11. Vraag 11 van 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?
    Toon antwoord

    Antwoord: 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. Vraag 12 van 15

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

    Antwoord: 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. Vraag 13 van 15

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

    Antwoord: B. 5/16 in

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

  14. Vraag 14 van 15

    Which of these drill bit sizes is the largest?
    Toon antwoord

    Antwoord: 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. Vraag 15 van 15

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

    Antwoord: 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.

Wat je moet weten voor het 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.

  • 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.

Veelgestelde vragen

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.

Is het certificaat geaccrediteerd of officieel erkend?

Nee. Het is een privé bewijs van deelname, alleen voor je kennis. Het is niet erkend, geaccrediteerd of goedgekeurd door een overheid, vergunningsinstantie, toezichthouder of onderwijsinstelling, en het vervangt geen wettelijk verplichte vergunning, certificering of opleiding.
