Yes!

9 can go both into 36 and 81 EQUALLY, let me show you

9, 18, 27, *36* , 45, 54, 63, 72, *81*, 90, 99

shadowlegendx · Answer

9 x 4 = 36 and 9 x 9 = 81

shadowlegendx · Answer

She can invite 9 friends

Each friend will get 4 water balloons and 9 beads

4 water balloons x 9 friends = 36

9 beads x 9 friends = 81

Get it?
