Question

Write a ratio for the following situation: 12 birds to 60 animals.

a) 1:5
b) 2:10
c) 3:15
d) 4:20

Answer 1

The simplest form of the ratio for 12 birds to 60 animals is found by dividing both numbers by 12, resulting in the ratio of 1:5. Thus, option a) 1:5 is the correct answer.

Step-by-step explanation:

To find the ratio of birds to all animals in the scenario where there are 12 birds to 60 animals, we need to simplify the numbers to their lowest terms. We divide both numbers by the greatest common divisor that they share, which in this case is 12, to find the simplest form of the ratio.

12 birds ÷ 12 = 1 bird
60 animals ÷ 12 = 5 animals

Therefore, the ratio of birds to all animals is 1:5. This can be confirmed as correct because if we multiply the ratio 1:5 by 12 (the number of birds), we would get 12:60, which is the original situation presented.

So, the correct option in the final answer is option a) 1:5.
