Some octopuses, some fish and a few
mermaids were happily frolicking in a rock
pool. Altogether there were 38 arms, 24 eyes
and 8 tails all swimming in the pool.
How many mermaids were there?

We have been solving a problem and trying to answer the question. We’ll the question “was how many mermaids were there?” There is 38 arms, 24 eyes and 8 tails. We know that there is 12 creatures all together. Our answer was three. There were three mermaids.

We worked like this.... We did 4 x 8 = 32 38-32 = 6.  

EYES- First we solved the eyes because all creatures have eyes. 24 - 2 =12

|

TAILS- If 8 creatures have tails then 4 creatures don’t have tails.

Now we know there are 4 octopuses

ARMS- 8 x 4 = 32 38 arms all together. now we have 6 arms 6 - 2 = 3 so 3 mermaids and 4 oct... 12 creatures 3 mermaids 5 fish so how many creature are there ? 12
