Answer:
18 bananas
Explanation:
for every 2 apples, there are 3 bananas.
So, if there are 12 apples then the original ratio of number of apples is being multiplied by 6
To prove this, 2 is the original ratio of apples and when 2 is multiplied by 6, you get 12 apples
To ensure the ratio of apples to bananas is the same, you multiply the original ratio of bananas by 3 as well. This leaves us with 18 bananas for every 12 apples (3*6 = 18)
To check if you are correct, you divide both the number of apples and the number of bananas by 6 and you get the original ratio, 2 to 3.
The ratio is essentially the same throughout except when you increase it by a constant ratio, it is no longer simplified but it is the same.
I tried explaining this the best I could and I really hope this made sense and helped!
