First I drew up a table and labeled the headings Zepts and zios. Then I started with 7 zepts and 1 zio but you need more than 1 of each. so I went down to 6 zepts but you couldn't get a whole number of zios. Then I went to 5 zepts but that didn't work either. then to 4 zepts and with that I got 8. It worked. I decided to see if there was more than 1 answer. I did 3 zepts and 2 zepts but they didn't work. The only answer was 4 zepts and 8 zios.
