Question

The ratio of students to parents is 1:4 respectively. If the

total number of people is 50, how many students are
there?

Answer 1

10 students

Explanation:

First find the sum of the ratio:

1 + 4 = 5

Number of students =
`(number in ratio)/(sum of ratio)` × total

=
`(1)/(5)` × 50

= 10

∴ 10 out of 50 are students.

( The rest are parents; 50-10=40parents )

Answer 2

• 10 students

Explanation:

Let the number of students is x, then the number of parents is 4x

Total number of people is 50:

• x + 4x = 50

Solve for x:

• 5x = 50
• x = 10

There are 10 students
