Answer:
16
Step-by-step explanation:
Given that:
For every 3 red roses bushes for every 4 yellow bushes are planted by Nana in her garden.
Let us first have a look at the ratio of red roses bushes and yellow bushes.
Number of red roses bushes : Number of yellow bushes = 3 : 4
Now, we are given that there are 12 red rose bushes planted.
To find: How many yellow rose bushes Nana will plant?
Solution:
Let us use unitary method for finding the required answer.
Number of yellow rose bushes for every 3 red roses = 4
Number of yellow rose bushes for every 1 red rose = [tex]\frac{4}{3}[/tex]
Number of yellow rose bushes for every 12 red rose = [tex]\frac{4}{3}\times 12 = 4\times 4 = \bold{16}[/tex]
Therefore, the answer is 16.
