    Answer:

    Step-by-step explanation:

    5 red

    15 black

    10 white

    altogether the is 30 marbles so that means it is ‘out of’  30

    and because the is 5 red it would be 5/30

    and because the is 10 white it would be 10/30

    that should be the answer but if you have to work the total all together then it would be 15/30

    hope this helps 🙂
