The ratio between the number of children (c) on a field trip and number of teachers (t) on the trips is 14/3. there are 70 children on the field trip. how many teachers are on the grip. (14/3 is in fraction form)

For this case we have a relationship of the form:
 
 There are 70 children on the field trip
 Therefore, we must replace the value of c = 70 in the equation.
 We have then:
 
 Clearing t, we have:
 
 
 there are 15 teachers on the trip
