A ...the number of announcements

Answer:
6 pelicans
Step-by-step explanation:
Let x = number of pelicans
Cody saw 4 times as many seagulls as pelicans:
⇒ number of seagulls = 4x
Total of 30 birds:
⇒ seagulls + pelicans = 30
⇒ 4x + x = 30
⇒ 5x = 30
⇒ x = 6
Therefore, there were 6 pelicans (and 24 seagulls).
If you simplify 24/40:
divide by 4
6/10
divide by 2
3/5
simplify 5/10:
divide by 2
1/5
therefore, 24/40 = 3/5 and 5/10 = 1/5 so 24/40 is 2/5 greater than 5/10
