Temaquiz 1: Fractions, decimals and the tape measure

  1. Fråga 1 av 15

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

    Svar: B. 12

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

  2. Fråga 2 av 15

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

    Svar: 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. Fråga 3 av 15

    What is 7/8 in as a decimal?
    Visa svar

    Svar: 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. Fråga 4 av 15

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

    Svar: 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. Fråga 5 av 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?
    Visa svar

    Svar: D. 60 3/8 in

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

  6. Fråga 6 av 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?
    Visa svar

    Svar: 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. Fråga 7 av 15

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

    Svar: 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. Fråga 8 av 15

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

    Svar: 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. Fråga 9 av 15

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

    Svar: 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. Fråga 10 av 15

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

    Svar: D. 1.047 m

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

  11. Fråga 11 av 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?
    Visa svar

    Svar: 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. Fråga 12 av 15

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

    Svar: 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. Fråga 13 av 15

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

    Svar: B. 5/16 in

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

  14. Fråga 14 av 15

    Which of these drill bit sizes is the largest?
    Visa svar

    Svar: 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. Fråga 15 av 15

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

    Svar: 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.

Vanliga frågor

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.

Är intyget ackrediterat eller officiellt erkänt?

Nej. Det är ett privat kursintyg, bara för dina kunskaper. Det är inte erkänt, ackrediterat eller godkänt av någon myndighet, tillståndsmyndighet, tillsynsmyndighet eller utbildningsinstitution, och det ersätter inte någon licens, certifiering eller utbildning som krävs enligt lag.
