brought to my attention by one of Ed Southall's tweets (thanks) @solvemymaths

the name is created by Michael Jacobs who has many Yohakus,

for integers, decimals and directed numbers as well as fractions,

with multiplication as well as addition

2 by 2 up to 4 by 4 grids

and algebriac expression multiplication

these are simple but highly effective puzzles that involve practice of a variety of skills

the powerpoint suggests a way to tackle these particular fraction puzzles (Egyptian fractions)

(there might be more than one solution to some of these?)
