    Hi, I do not know how to answer this, can someone please help?

    "A bag contains red and blue balls. The probability of picking a blue ball is 5/9. There are more than 10 balls in this bag. Write down how many red balls could be in this bag?"

    This is year 9 Maths question.

    Thank you!

    4 times any integer greater than 1. I dunno. Quite a weird question.

    just times it by two, because it says how many could be in the bag, there is more than one answer. So , make the denominator more than 10,

    (5/9)x2=10/18 so there could be 10 red balls in the bag...

    It's quite a weird question to be honest, but anyway hope this helped

    10/18 looks a good method to solve it, so red ball is 8.

    Thanks zwastix and Chef289 for help!

    best regards!
