6/.1=60 tiles are required.

1. how many tils 10 cm square do you need to cover a room 2m by 3m?
2m = 200 cm
3m = 300 cm
2m x 3m = 200 cm x 300 cm = 60,000 sq cm
----------
The 10 cm time has 10 cm x 10 cm = 100 sq cm
----------
# of times needed is 60,000/100 = 600
===========================

2. if there are 6 tutors and 42 students, what is the ratio of staff to students?
staff/students = 6/42 = 1/7 or 1:7
==============
Cheers,
