Question

Seven out of every 10 students at Round Lake school district ride a school bus. If there are 2000

students in the school district, how many students ride a school bus?

Answer 1

1400 students ride the school bus

Solution:

Given that Seven out of every 10 students at Round Lake school district ride a school bus

There are 2000 students in the school district

To find: number of students ride school bus

Let "x" be the number of students ride the school bus

We can solve this sum by setting up a proportion

`(7)/(10) = \frac{\text{ number of students ride in school bus}}{\text{ total number of students}}`

`(7)/(10) = (x)/(2000)`

On cross multiplying we get,

`7 * 2000 = 10 * x\\\\14000 = 10x\\\\x = 1400`

Thus 1400 students ride the school bus
