Oplossing - Solution

Je kan op twee manieren de helft nemen van een breuk :
→ ofwel de teller delen door 2
→ ofwel de noemer vermenigvuldigen met 2
\( \text{De helft van } \frac 94 \text{ is } \frac 98 \\ \text{De helft van } \frac 32 \text{ is } \frac 34 \\ \text{De helft van } \frac {4}{26} \text{ is } \frac {2}{26} = \frac {1}{13} \)
