Question

Write and solve an equation using the constant of proportionality to answer each question.

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 trip?

Answer 1

`(c)/(t ) = (14)/(3)`

as c=70 so put value of c in above formula we get

`(70)/(t) = (14)/(3)`

by cross multiplication

`70 * 3 = 14t`

`210 = 14t`

`(210)/(14) = t`

t=15

i hope u will understand

Answer 2

15 teachers

Explanation:

Given:

number of children is c

number of teachers is t

`(c)/(t)` =
`(14)/(3)` (rearrange)

t =
`(3)/(14)` x C

When C = 70,

t =
`(3)/(14)` x 70

t = 15 teachers
