Question

there are 4 teachers for every 100 students at Brians school. if there are 950 students, write and solve a proportion showing how many teachers are at the school

Answer 1

Explanation:

We can set up the proportion with students on the bottom and teachers on the to

`(4)/(100) = (x)/(950)`

Now we cross multiply

`100x = (950)(4)`

`100x = 3800`

Lastly, we will divide both sides by 100

`x = 38`
