Вопрос 63

Which multiplication statements are true? Select all that apply.

  1. 0.7 × 0.5 = 0.35Правильный ответ
  2. 2.4 × 0.5 = 1.2Правильный ответ
  3. 0.6 × 0.3 = 1.8
  4. 4.2 × 0.1 = 4.2

Объяснение

Multiplying 0.6 by 0.3 gives 0.18: multiply 6 by 3 to get 18, then place two decimal places because the factors contribute one each. The wrong answer 1.8 places the decimal point one position too far right, keeping only one of the two contributed places.
