  1. Which value is greatest: 3/4, 0.7, 72%, or 7/10?

    Answer: 3/4

    3/4 = 0.75, which is greater than 0.72, 0.70, and 0.70.

  2. If A = 2^5 and B = 5^2, which statement is true?

    Answer: A > B

    2^5 = 32 and 5^2 = 25, so A > B.

  3. A store sells 3 items for $7.50. Another sells 5 items for $12.00. Which store has the lower unit price?

    Answer: Second store ($2.40 each)

    First store: $7.50/3 = $2.50; second store: $12.00/5 = $2.40, so the second store is cheaper.

  4. Compare: √81 vs. 9.1 — which is larger?

    Answer: 9.1

    √81 = 9.0 exactly, which is less than 9.1.

  5. Column A: 15% of 200. Column B: 25% of 120. Which is greater?

    Answer: They are equal

    15% of 200 = 30 and 25% of 120 = 30, so they are equal.

  6. Which fraction is smallest: 5/8, 3/5, 11/20, or 7/12?

    Answer: 11/20

    Converting to decimals: 5/8=0.625, 3/5=0.600, 11/20=0.550, 7/12≈0.583, so 11/20 is smallest.

  7. A car travels 180 miles in 3 hours; another travels 260 miles in 4 hours. Which has the higher average speed?

    Answer: Second car (65 mph)

    First car: 180/3 = 60 mph; second car: 260/4 = 65 mph, so the second car is faster.
