Quiz tematyczny 1: Fractions, decimals and the tape measure

  1. Pytanie 1 z 15

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

    Odpowiedź: B. 12

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

  2. Pytanie 2 z 15

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

    Odpowiedź: 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. Pytanie 3 z 15

    What is 7/8 in as a decimal?
    Pokaż odpowiedź

    Odpowiedź: 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. Pytanie 4 z 15

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

    Odpowiedź: 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. Pytanie 5 z 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?
    Pokaż odpowiedź

    Odpowiedź: D. 60 3/8 in

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

  6. Pytanie 6 z 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?
    Pokaż odpowiedź

    Odpowiedź: 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. Pytanie 7 z 15

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

    Odpowiedź: 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. Pytanie 8 z 15

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

    Odpowiedź: 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. Pytanie 9 z 15

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

    Odpowiedź: 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. Pytanie 10 z 15

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

    Odpowiedź: D. 1.047 m

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

  11. Pytanie 11 z 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?
    Pokaż odpowiedź

    Odpowiedź: 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. Pytanie 12 z 15

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

    Odpowiedź: 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. Pytanie 13 z 15

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

    Odpowiedź: B. 5/16 in

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

  14. Pytanie 14 z 15

    Which of these drill bit sizes is the largest?
    Pokaż odpowiedź

    Odpowiedź: 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. Pytanie 15 z 15

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

    Odpowiedź: 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.

  • 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.

Najczęściej zadawane pytania

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.

Czy zaświadczenie jest akredytowane lub oficjalnie uznawane?

Nie. To prywatne zaświadczenie o ukończeniu, wyłącznie dla Twojej wiedzy. Nie jest uznawane, akredytowane ani zatwierdzone przez żaden rząd, organ licencyjny, regulatora ani instytucję edukacyjną i nie zastępuje żadnej licencji, certyfikacji ani szkolenia wymaganych przez prawo.
