  1. A job requires 4 2/3 hours. A worker completes 1 1/3 hours. How much time remains?

    Answer: 3 1/3 hours

    4 2/3 − 1 1/3 = 3 1/3 hours.

  2. A decimal torque reading is 14.625 ft-lbs. Expressed as a mixed number, this is:

    Answer: 14 5/8 ft-lbs

    0.625 = 625/1000 = 5/8, so 14.625 = 14 5/8 ft-lbs.

  3. If 3/5 of the elevator's travel time is spent ascending, what fraction is spent descending?

    Answer: 2/5

    1 − 3/5 = 2/5 of time is spent descending.

  4. A hydraulic cylinder extends 0.045 inch per psi. How far does it extend at 200 psi?

    Answer: 9.0 inches

    0.045 × 200 = 9.0 inches.

  5. A mechanic uses 2/3 of a box of grease cartridges containing 12 cartridges. How many cartridges were used?

    Answer: 8

    2/3 × 12 = 8 cartridges.

  6. Two elevator cables are 18.75 feet and 22.5 feet long. What is the total length?

    Answer: 41.25 feet

    18.75 + 22.50 = 41.25 feet.

  7. A counterweight is 7/10 of the car weight plus half the capacity load. If car weight is 2,000 lbs and half capacity is 500 lbs, the counterweight is:

    Answer: 1,900 lbs

    7/10 × 2,000 + 500 = 1,400 + 500 = 1,900 lbs.
