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 child

Mrrafil [7]

For this case we have a relationship of the form:
$c / t = 14/3
$
There are 70 children on the field trip
Therefore, we must replace the value of c = 70 in the equation.
We have then:
$70 / t = 14/3
$
Clearing t, we have:
$t = (3/14) * (70)

t = 15$
Answer:
there are 15 teachers on the trip
