The ratio of students to parents is 1:4 respectively. If the total number of people is 50, how many students are
there?

10 students

Step-by-step explanation:

First find the sum of the ratio:

1 + 4 = 5

Number of students = × total

= × 50

= 10

∴ 10 out of 50 are students.

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

6(h+1)/2=a

a=area
