I got a couple of questions that I tried really hard to do but I still think it's wrong.
Here are the questions,
1. "If a single roll of wallpaper will cover 3 square meters, how many single rolls will it take to cover a wall 2 meters x 5 meters?"
2. "If a customer buys 2kg. of nails at 16cents a kg., how much would the nails cost?"
3. "If ceramic tiles are 203mm x 203mm, how many tiles would it take to cover an area 1 meters x 2 meters?"
