    Answer:

    No. of yellow balloons = r – b – \frac{b}{2}

    Step-by-step explanation:

    Total number of balloons = r

    No of blue balloons = b

    Blue balloons are twice the no of green balloons. so

    No. of green balloons = \frac{b}{2}

    No of yellow balloons = ( Total number of balloons ) – ( No of blue balloons ) – ( No. of green balloons )

    No. of yellow balloons = r – b – \frac{b}{2}
