Oink and Cluck

Today and on Friday we have been doing a problem in buddies. The name of it is Oink and Cluck. So someone is driving along the road but then tones of pigs and chickens were in front of his car. He counted 36 legs so we had to turn that into the amount of pigs and chickens there are. So a pig has four legs and a chicken has two. It's a little hard to find out how many there is but we manage to get four. My buddy was Mitchel. We found three answers what we got doing this.

4x9=36 so there's 9 Pigs.

2x18=36 so there's 18 Chickens.

18+18=36 so there's 4 Pigs and 7 Chickens.

20+16=36 so there's 10 Chickens and 4 Pigs.
