Pregunta 63

Which multiplication statements are true? Select all that apply.

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

Explicación

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.
