A complete set of sheep is 9 whites + 1 black = 10 sheep.

How many sets of 10 in 180 ? Looks like 18 sets.

In 18 sets you have 18 black and 18 x 9 = 162 white.

9+1 is 10. So 180/10 is 18. There are 18 groups of 9 white sheep, and 18 groups of 1 black sheep.

1. There are 162 white sheep
2. There are 18 black sheep
