blessedami:=============My DD wonders how it can be 10!
The question was : X needs 200 pieces of ribbons each of them measuring 110 cm. Each roll of ribbon has 25 metres. How many rolls of ribbon are needed?
200*110= 22000 cm ( 220 m)
220/25=8.8 which is approximately 9
You can only make 22 ribbons from each roll. Remaining 80cm will be scrapped.
9 rolls for198 ribbons
The 10th roll only used it for 2 ribbons (tricky question)
