  1. A utility crew completes 3/8 of a job on Monday and 1/4 on Tuesday. What fraction of the job remains?

    Answer: 3/8

    3/8 + 1/4 = 3/8 + 2/8 = 5/8 done, so 1 − 5/8 = 3/8 remains.

  2. If a wire costs $0.45 per foot, how much do 240 feet cost?

    Answer: $108.00

    0.45 × 240 = $108.00.

  3. A transformer operates at 85% efficiency. If 4,000 watts enter, how many watts are output?

    Answer: 3,400 W

    4,000 × 0.85 = 3,400 watts output.

  4. What is 15% of 320?

    Answer: 48

    0.15 × 320 = 48.

  5. A technician works 6.5 hours at $18/hr and 3 hours overtime at 1.5× regular pay. What is the total pay?

    Answer: $189.00

    Regular: 6.5 × $18 = $117; overtime: 3 × $27 = $81; total = $198, closest answer is $189 — wait, let me recalculate: 6.5×18=117, 3×27=81, total=198. The answer is $198.00.

  6. Express 0.625 as a fraction in its simplest form.

    Answer: 5/8
