Respuesta :
it should be 125/5 is 25
so now we know each 1/5 os 25
in order to find 35 we multiply 25 by 3
25 x 3 is 75
75 students HAVE a mobile phone
now subtract 125-75 and you should get 50
final answer is 50
50 do not have a mobil phone.....
125/5=25
SO...do 25*3=75
THEN...125-75=(50)
125/5=25
SO...do 25*3=75
THEN...125-75=(50)
