No. of balloons Perrry broke = x
No. of balloons Paula broke = (1/2)x --> 1%2F2 as many balloons as Perry.

Perry%2BPaula=18
x%2B%281%2F2%29x=18
x%281%2B1%2F2%29=18 ---> cross%281.5%29x%2Fcross%281.5%29=cross%2818%2912%2Fcross%281.5%29
highlight%28x=12balloons%29 ---> Perry broke

%281%2F2%29x=%281%2F2%29%2812%29=highlight%286balloons%29 ---> Paula broke

Check,
Perry%2BPaula=18
12%2B6=18
18=18
Thank you,
