Lily has 12 balloons. 5 are blue, 3 are red and the rest are green. What fractions of the balloons is green? Give your answer in its simplest form.

Total balloons = 12

Let x = # of green balloons

12 = 5+3+x
12 = 8+x
x= 4

# of green balloons/total balloons = 4/12 = 1/3

1/3 of the balloons are green.

To find the fraction of balloons that are green, we need to determine how many balloons are green.

Given that Lily has 12 balloons, we know that 5 are blue and 3 are red.

To find the number of green balloons, we subtract the number of blue and red balloons from the total number of balloons:

12 - 5 - 3 = 4

So, Lily has 4 green balloons.

To find the fraction of balloons that are green, we divide the number of green balloons by the total number of balloons:

4 / 12

This fraction can be simplified by dividing both the numerator and denominator by their greatest common divisor, which is 4:

4 ÷ 4 / 12 ÷ 4 = 1/3

Therefore, the fraction of balloons that are green is 1/3.

To find the fraction of balloons that are green, we need to know the total number of green balloons. We can find this number by subtracting the number of blue and red balloons from the total number of balloons Lily has.

Total balloons = 12
Blue balloons = 5
Red balloons = 3

To find the number of green balloons, we subtract the sum of blue and red balloons from the total:
Green balloons = Total balloons - Blue balloons - Red balloons
Green balloons = 12 - 5 - 3
Green balloons = 4

Now that we know the number of green balloons is 4, we can express it as a fraction of the total number of balloons. The fraction is calculated by dividing the number of green balloons by the total number of balloons.

Fraction of green balloons = Green balloons / Total balloons
Fraction of green balloons = 4 / 12

To simplify this fraction, we can divide both the numerator and denominator by their greatest common divisor, which is 4.

4 / 12 = (4 ÷ 4) / (12 ÷ 4) = 1 / 3

So, the fraction of balloons that are green is 1/3.
