Luc is painting the doors in his house. He uses 4 3 of a tin of paint for each door. Work out the least number of tins of paint Luc needs to paint 7 doors.
If you use 4/3 of a tin for each door that is more than one whole tin.
They must be BIG doors.
4/3*7= = 9.3333333333333333
So 10 cans will be needed.
