Marla, jamie, and sarah have each led their book club’s monthly meeting. jamie has led 2/6 of the meetings, and sarah has led 1/6 of the meetings. what fraction of the meetings has marla led?

Marla led 3/6 of the meetings (1/2 the meetings)

Explanation:
The total percentage of meetings is 100% which is equal to 1 as a fraction.
This means that if we add the fraction of meetings Marla conducted, fraction of meetings Jamie conducted and fraction of meetings Sarah conducted, we will get 1.
We are given that:
Fraction of meetings Jamie conducted = 2/6
Fraction of meetings Sarah conducted = 1/6
Therefore:
1 = Fraction of meetings Marla conducted + 2/6 + 1/6
Fraction of meetings Marla conducted = 1 - (2/6 + 1/6)
Fraction of meetings Marla conducted = 1 - 3/6
Fraction of meetings Marla conducted = 3/6 = 1/2

Hope this helps :)
