Answer:
In the first novel, A Princess of Mars, John Carter of Virginia somehow mentally projects himself to the dying planet Mars, known to its various native races as "Barsoom", where he has death-defying adventures, romances the eponymous princess, and saves the world. The novel was a hit, and a series of ten sequels followed over the course of the next few decades, initially chronicling the further adventures of John Carter before shifting their focus to other Martian characters.

you could split the boys in half by 2 groups of 7 then use one of those seven group and add it to the 21 girls which is 28. Then divide 28 by 7 and you get 4. So there is 5 with 7 members in each. A more easy way of doing it is adding 14 and 21 together and you get 35 and 7x5 is 35. You can also do 7 groups of 5.
