Answer: He needs 6 more matches to win for the team.

In total, he needs 16 matches to win for the team to have 55% success rate.

Step-by-step explanation:

Since we have given that

Total number of matches = 28

Number of matches till now = 10

If the success rate = 55%

Then, Number of matches he won is given by

$\dfrac{55}{100}\times 28\\\\=0.55\times 28=15.4$

So, he needs 15.4-10 = 5.4 matches more to win for the team

To be exact he needs 6 more matches to win for the team.
