Question

There are 3 red balloons, 2 white and 4 blue balloons and one balloon of each colour bursts. What fraction of the total number of balloons are now blue?

Answer 1

Initially there are

3 red balloons
2 white balloons
4 blue balloons

After bursting, there are

2 red balloons
1 white balloon
3 blue balloons
Total number of Balloons = 2+1+3
= 6
We know that fraction = $\frac{Part}{Whole}$
So in our case = $\frac{BlueBalllons}{TotalBalloons}$
$\therefore$ the fraction of blue balloons = $\frac{3}{6}$
