Question:

The ratio of students to teachers at a school is 19 : 1. How many students are there in each total number of people?

A: 100 people

b. 280 people

c.440 people

d.760 people

Answer:

A )95 students and 5 teachers

B)266 students and 14 teachers

C)418 students and 22 teachers

D)722 students and 38 teachers

Explanation:

A: 100 people

Ratio = 19 : 1

The sum of the ratio is 19 + 1 = 20

Scale factor =
`(100)/(20)`

scale factor = 5

The number students is
`19 * 5` = 95

The number of teachers is
`1 * 5` = 5

b. 280 people

Ratio = 19 : 1

The sum of the ratio is 19 + 1 = 20

Scale factor =
`(280)/(20)`

scale factor = 14

The number students is
`19 * 14` = 266

The number of teachers is
`1 * 14` = 14

c.440 people

Ratio = 19 : 1

The sum of the ratio is 19 + 1 = 20

Scale factor =
`(440)/(20)`

scale factor = 22

The number students is
`19 * 22` = 418

The number of teachers is
`1 * 22` = 22

d.760 people

Ratio = 19 : 1

The sum of the ratio is 19 + 1 = 20

Scale factor =
`(760)/(20)`

scale factor = 38

The number students is
`19 * 38` = 722

The number of teachers is
`1 * 38` = 38
