Question

a school needs 3 teachers for every 70 children. They expect to have 14,700 children. at this time they have 612 teachers. How many more teachers are needed ?

Answer 1

First of all, set up a ratio.
A good ratio is 3/70.
We don't know how many teachers they will need total, so let's call that x.
The number of students we have is 14700.
So we can write the equation
\[\frac{3}{70} = \frac{x}{14700}\]

Answer 2

x-612 will tell them how many more teachers are needed

Answer 3

I should mention that you have to do the proportion that was set up by SmoothMath first and then do what I mentioned above (Mine is step 2)

Answer 4

im still lost..

Answer 5

first statement allows us to create this ratio
