Gap-fill

Ask the student a question, and give any hints about how they should answer this part.

Ermitteln Sie für beide Brüche eine Darstellung als ägyptische Bruchzahl (als Summe von Stammbrüchen)!

$\var[fractionNumbers]{d}$ =FirstUnitFraction $\quad\var[fractionNumbers]{f}$ = SecondUnitFraction

Hinweis: Notieren Sie in der folgenden Form 1/9+1/16+...

Advice

a) Mögliche Lösungen sind (es gibt verschiedene Darstellungen):

$\var[fractionNumbers]{d}=\var[fractionNumbers]{a}+\var[fractionNumbers]{b}+\var[fractionNumbers]{c}$ und $\var[fractionNumbers]{f}=\var[fractionNumbers]{h1}+\var[fractionNumbers]{b}+\var[fractionNumbers]{h2}$

b) $\var[fractionNumbers]{g}$

Give a worked solution to the whole question.
