Out of 43 children, 15/17 of the boys can swim and 2/9 cannot swim, only 6 of the children cannot swim, how many boys can swim?

Let's break down the problem step-by-step to find out how many boys can swim.

1. **Total number of children:**
   \( 43 \)

2. **Number of children who cannot swim:**
   \( 6 \)

3. **Number of children who can swim:**
   \[
   43 - 6 = 37
   \]

4. **Let \( B \) be the total number of boys.**

5. **Number of boys who can swim:**
   \[
   \frac{15}{17} \times B
   \]

6. **Number of boys who cannot swim:**
   \[
   \frac{2}{9} \times B
   \]

We know that the total number of children who cannot swim is 6. Since \( \frac{2}{9} \) of the boys cannot swim, we can set up the following equation:
   \[
   \frac{2}{9} \times B = 6
   \]

Solving for \( B \):
   \[
   B = 6 \times \frac{9}{2}
   \]
   \[
   B = 27
   \]

So, there are 27 boys in total.

7. **Number of boys who can swim:**
   \[
   \frac{15}{17} \times 27
   \]

Calculating this:
   \[
   \frac{15}{17} \times 27 = \frac{15 \times 27}{17} = \frac{405}{17} \approx 23.82 \approx 24
   \]

Therefore, the number of boys who can swim is approximately 24.
