### Instruction:
There were 672 balloons that were either green, blue, yellow, or red. They were divided into equal groups and then Anya took half of the yellow ones home. How many balloons did Anya take home?

### Response:
 Kulikuwa na maballoni 672/4 = <<672/4=168>>168 katika kila rangi.
Anya alichukua nusu ya maballoni ya njano, ambayo inamaanisha 168 * (1/2) = 84 maballoni.
