Number (patterns): Hungry Bear

Further Challenges

• I wonder what would happen if…

Barney the black bear became even more fussy about the food he scavenged, and threw away two out of every eight items that he found in the bins (and ate the remaining items).

If Barney removed a total of 112 food items, how many did he eat this time?

Barney’s best friend, Beatrix, was rummaging through some bins in another neighbourhood. She threw away three out of every seven food items found (and ate the remaining items).

If Beatrix through away 12 items, how many food items did she remove from the bins in total?
