For the party, 105 re and blue balloons were inflated. There were 3 red balloons for every 2 blue balloons. How many blue balloons are there?
105/5=21
21*2=42 blue
21*3=63 red
To find the number of blue balloons, we can set up a proportion based on the given information.
We know that there were 3 red balloons for every 2 blue balloons. So, we can write the ratio as:
3 red balloons / 2 blue balloons
Now, let's assign variables to the unknown quantities. Let's say the number of blue balloons is x.
Then, we can set up the proportion:
3 / 2 = 105 red balloons / x blue balloons
To solve for x, we cross-multiply:
3x = 2 * 105
3x = 210
Divide both sides by 3:
x = 70
Therefore, there are 70 blue balloons.
