Answer:

Pedro spent 9 weeks with his uncle and his friend.

Step-by-step explanation:

First, you need to find the amount of weeks Pedro spent with his friend. The statement indicates that he spent two weeks more with his friend than with his uncle which means that you have to add the number of weeks he spent with his uncle plus 2, which you can show in a number line:

$3\frac{1}{2}$ 2

1 2 3 4 5 6 7 8 9 10

$3\frac{1}{2}+2=5\frac{1}{2}$

Now, you can find the and answer by adding up the number of weeks he spent with his uncle plus the weeks he spent with his friend:

$3\frac{1}{2}$ $5\frac{1}{2}$

__________________________________

1 2 3 4 5 6 7 8 9 10

$3\frac{1}{2} + 5\frac{1}{2}=9$

According to this, the answer is that Pedro spent 9 weeks with his uncle and his friend.

and the water would be 20/50=0.4 or 40% of the total mixture.
