126
Step-by-step explanation:
From the statement , we have been given given
blue jays : black crows : red robins : cardinal
That is :
59 : 68 : 12 : 1
Total ratio = 59 + 68 + 12 + 1 = 140
Therefore : the number of blue jays if 300 visit is :
ratio of blue jay / total ratio x 300
That is
59/140 x 300
= 126. 4285714
≈ 126
