اختبار الموضوع 1: Fractions, decimals and the tape measure

  1. السؤال 1 من 15

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

    الإجابة: B. 12

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

  2. السؤال 2 من 15

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

    الإجابة: 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. السؤال 3 من 15

    What is 7/8 in as a decimal?
    أظهر الإجابة

    الإجابة: 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. السؤال 4 من 15

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

    الإجابة: 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. السؤال 5 من 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?
    أظهر الإجابة

    الإجابة: D. 60 3/8 in

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

  6. السؤال 6 من 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?
    أظهر الإجابة

    الإجابة: 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. السؤال 7 من 15

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

    الإجابة: 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. السؤال 8 من 15

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

    الإجابة: 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. السؤال 9 من 15

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

    الإجابة: 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. السؤال 10 من 15

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

    الإجابة: D. 1.047 m

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

  11. السؤال 11 من 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?
    أظهر الإجابة

    الإجابة: 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. السؤال 12 من 15

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

    الإجابة: 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. السؤال 13 من 15

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

    الإجابة: B. 5/16 in

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

  14. السؤال 14 من 15

    Which of these drill bit sizes is the largest?
    أظهر الإجابة

    الإجابة: 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. السؤال 15 من 15

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

    الإجابة: 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.

ما يجب معرفته قبل الاختبار

  • 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.

الأسئلة الشائعة

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.

هل الشهادة معتمدة أو معترف بها رسميًا؟

لا. إنها شهادة إتمام خاصة للمعرفة فقط. وهي غير معترف بها أو معتمدة أو موافق عليها من أي حكومة أو جهة ترخيص أو هيئة تنظيمية أو مؤسسة تعليمية، ولا تحل محل أي رخصة أو شهادة أو تدريب يفرضه القانون.
