Answer:

A. 11/15 B. Ibai.

Explanation:

First, find the Least Common Multiple, or LCM, of the denominators, which is 15. Then, multiply each denominator by the number that gets the denominator to 15, which is the LCM. Next, multiply the numerator by the same number you multiplied the denominators, which was 3 for Ibai, and 5 for Ane. Finally, compare the two numbers to see which is higher. In this case, Ibai took out 6/15, while Ane took out 5/15, meaning Ibai took out more than Ane. Also, together, Ibai and Ane both drew out 11/15 together.

Answer:

7/15

Explanation:

2/5 + 1/3 is the same as 2/5 + 5/15.. so we add them together to get 7/15. This can not be simplified further

To know who has gotten most I like to think in percentage terms. 2/5 is the same as 40% (2/5 is the same as 4/10 = 40/100 =40%). 1/3 is 33.33% so Ane got more
