How many shoes does Charlie wear? ** If Sophie wears size five shoes, Charlie wears 5 * shoe size 5 = shoe size <<5*5=25>>25
How many shoes do the two wear together? ** Their combined shoes size for the two is shoe size 25 + shoe size 5 = <<25+5=30>>30
What is the average shoe size the two wear? ** The average for the shoe size the two wear is shoe size 30/2 = shoe size <<30/2=15>>15
