First 45 / 10
that is exactly 4.5 meaning there are 4.5 groups of 10 red balloons
63 / 4.5 is 14
There will be 14 blue balloons for every 10 balloons.
Hope this helps :)

Answer: 40%
Step-by-step explanation:
first you symplify your fraction:
12/30 = 2/5
then divide your numerator from your denominator:
2÷5 =0.4
then you convert your decimal into a percentage:

Answer:
The value of x in terms of a, b ans c is ![x=\frac{ac-ab}{2}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7Bac-ab%7D%7B2%7D)
Step-by-step explanation:
We have given the expression ![\frac{2x}{a}+b=c](https://tex.z-dn.net/?f=%5Cfrac%7B2x%7D%7Ba%7D%2Bb%3Dc)
We have to find the value of x in terms of a, b and c
So ![\frac{2x}{a}+b=c](https://tex.z-dn.net/?f=%5Cfrac%7B2x%7D%7Ba%7D%2Bb%3Dc)
![\frac{2x}{a}=c-b](https://tex.z-dn.net/?f=%5Cfrac%7B2x%7D%7Ba%7D%3Dc-b)
![2x=a(c-b)](https://tex.z-dn.net/?f=2x%3Da%28c-b%29)
![2x=ac-ab](https://tex.z-dn.net/?f=2x%3Dac-ab)
![x=\frac{ac-ab}{2}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7Bac-ab%7D%7B2%7D)
So the value of x in terms a ,b and c is ![x=\frac{ac-ab}{2}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7Bac-ab%7D%7B2%7D)
Answer:
