There are some spiders and ants in a container.
20% of the total number of creatures are spiders.
Tom counted a total of 192 legs.
How many spiders and ants are there altogether?

Have fun,
Mrs R

  1. I think it has something to do with one of the heuristic skills we've learnt...(And I know what is it!)

    Anyway, who would want to keep so many spiders and ants in a container? Whoever that person is, he or she must be VERY obsessed with arachnids and insects.

  2. Can someone help me with this? Mrs R said if 20% of the total number of creatures are spiders, that means 1/5 are spiders. Remaining 4/5(80%) are ants. Sounds like supposition to me but I cam't just seem to work it out

    1. If Spiders are 20% and Ants are 80%,so ants would have how many times more than Spiders? Do you feel this way would be easier?
