If i buy 3.5 meters of ribbon how many laces can i make if i need 15.5 cm per each lace

1 meter = 100 cm

So 3.5*100=350 cm

Next divide 350 by the 15.5 cm and you should get 22.580 and so on, however you are only required to find how many you can make (the whole number) so therefore the answer is

22

(If you do need to add the decimal it's either 22.58 or 22.6 or 22.50
