Caitriona, Karim, Saloni, Matthew, Vipul and Sydney from Maadi
    British International School in Cairo used fraction strips to
    help find solutions to this problem. Georgina from Ruyton Girls
    School in Melbourne, Australia also sent correct sums of unit
    fractions $${3\over 4} = {1\over 4} + {1\over 2} $$ or
    $${1\over 12} + {1\over 6} + {1\over 2}$$ or $${1\over 3} +
    {1\over 4} + {1\over 6} $$ $${2\over 3} = {1\over 6} + {1\over
    2}$$ or $${1\over 12} + {1\over 3} + {1\over 4}$$ I wonder if
    you can find any other fractions which can be made as the sum
    of unit fractions?<br />
