Answers

  2. Answer:
    Callie multiplied incorrectly
    Step-by-step explanation:
    Here we have 0.42 × 4.73 = 1.9866 then
    1.9866 + 29.4 + 168 = 199.3866
    we had 0.42 × 4.73 = 1.26 which is incorrect meaning that Callie multiplied incorrectly
    Callie multiplied as follows
    0.42 × 3 = 1.26 but what was in the question was
    0.42 × 4.73 which is equal to 1.9866.
