    Question:

    Ania bought two books in a bookstore and paid 37.20, and Jurek paid three times more for his. How much did Jurek pay?

    Step-by-step explanation:

    This is a question on multiplying decimals by natural numbers.

    Number if books bought by Ania = 2

    Cost for the two books = 37.20

    Jurek paid = 3 times the amount Ania paid

    Amount Jurek paid = 3*37.20

    To multiply decimals with whole numbers, first multiply without the decimals

    3*3720 = 11160

    3 has no decimal place

    37.20 has 2 decimal place

    Therefore the answer would be in two decimal place = 111.60

    So 3 * 37.2 = 111.60
