Given:
Number of red balloons = L
Number of green balloons = M
If they were divided evenly among 3 kid, let's find the amount each kid gets.
To find the number of balloons each kid gets, apply the formula:
[tex]\text{ number each kid gets = }\frac{total\text{ number of ballons}}{number\text{ of children}}[/tex]Hence, we have:
[tex]\text{ number each kid gets = }\frac{L+M}{3}[/tex]ANSWER:
[tex]\frac{L+M}{3}[/tex]
