Some penguins were playing on the ice. Ten dove into the water. A few seconds later, six jumped back onto the ice. Now there are 12 penguins on the ice. How many penguins were on the ice to start?
if ten dove int the water and 6 came back up there would be 4 left in the water.If there are now 12 penguins on the ice then there were 16 penguins to begin with.
