Sarah was calculating the cost of 12 pencils. She knew that each pencil costs £0.45, but she accidentally placed the decimal point in the wrong place and calculated the total cost as £540. How many times more is Sarah's incorrect total compared to the correct total?

    Sarah's incorrect total is 1,000 times more than the correct total.

    Correct total cost = 12 pencils × £0.45 = £5.40
    Sarah’s incorrect total = £540
    £540 ÷ £5.40 = 100 times more
    But since Sarah misplaced the decimal by three places, the incorrect total is actually 1,000 times more than the correct total.
