  1. A worker completes 3/8 of a job in 6 hours. At this rate, how many hours will the entire job take?

    Answer: 16 hours

    If 3/8 of the job takes 6 hours, then 1/8 takes 2 hours, and 8/8 (the whole job) takes 8 × 2 = 16 hours.

  2. If a cable costs $2.40 per foot, how much does 37.5 feet cost?

    Answer: $90.00

    37.5 × $2.40 = $90.00.

  3. A conduit run requires 4 sections of pipe. The sections measure 8¾ ft, 6½ ft, 11¼ ft, and 9 ft. What is the total length?

    Answer: 35 ft

    8¾ + 6½ + 11¼ + 9 = 8.75 + 6.5 + 11.25 + 9 = 35.5 ft.

  4. Out of 240 workers on a job site, 15% are apprentices. How many apprentices are there?

    Answer: 36

    15% of 240 = 0.15 × 240 = 36.

  5. If an apprentice earns $22.50 per hour and works 8.5 hours, what is the gross pay?

    Answer: $191.25

    22.50 × 8.5 = 22.50 × 8 + 22.50 × 0.5 = 180 + 11.25 = $191.25.

  6. A circuit has a resistance that increases by 12.5% when heated. If the original resistance is 80 ohms, what is the new resistance?

    Answer: 90 ohms

    12.5% of 80 = 0.125 × 80 = 10. New resistance = 80 + 10 = 90 ohms.
