Step-by-step explanation:
Answer:
Red color= 28 balloon
Blue color= 14 balloon
White color= 7 balloon
Step-by-step explanation:
Given: There are 49 balloons
As given, there are 2 red balloon equal to the number of blue balloon
∴ 
Again given, there are 1/2 white balloon equal to the number of blue balloon.
∴ 
As above equation, we can understand that:

multiplying both side by 2
⇒ 
which mean, if we have 2 blue balloon then we will have 4 red and 1 white balloon.
∴ Total combination of all color of balloon= 
Now, checking how many number of times combination can we have in 49 balloon.

Next, finding number of balloon in each color.
Red color= 
Blues color= 
White color= 
It's 4:3 because if its 24:18 you can break it down by dividing 6 from both of them to get 4:3
