Hi, do you mind explaining why 15-2? 2 supposed to be teacher. Please if possible explain the steps.
Thank you.
Thank you.
@wk....
1 group have 15 pupils and 2 teachers.
1 group have 13 more pupils than teacher.
We can simplified as...
13 more pupils → 1 group
52 more pupils = 52÷13= 4 groups
1 group → 15 pupils
4 groups = 4×15 = 60 pupils.
