Question 40

Select all true calculations.

  1. 2.6 + 0.35 = 2.95Correct answer
  2. 4.8 + 0.06 = 4.14
  3. 7 - 1.28 = 5.72Correct answer
  4. 3.02 - 0.7 = 2.95

Explanation

Aligned arithmetic gives 2.60 + 0.35 = 2.95 and 7.00 - 1.28 = 5.72. The claims 4.8 + 0.06 = 4.14 and 3.02 - 0.7 = 2.95 come from lining up final digits instead of decimal points.
