Liiguta oranž täpp õige vastuse juurde.
Kuna \color{orange}{NUMBER} on positiivnenegatiivne, tuleb oranži täppi liigutada arvteljel nullist paremalevasakule.
Teisendame liigmurru \color{orange}{NUMBER} segaarvuks:
\color{orange}{NUMBER} = \color{blue}{M_NUMBER}
Seetõttu \color{blue}{M_NUMBER} asub arvteljel \color{green}{M_WHOLE} ja \color{green}{M_WHOLE + (SOLUTION > 1 ? 1 : -1)} vahel.
style({ stroke: "#FFA500", strokeWidth: 3.5 });
line( [M_WHOLE, -0.2], [M_WHOLE, 0.2]);
line( [M_WHOLE + (SOLUTION > 0 ? 1 : -1), -0.2], [M_WHOLE + (SOLUTION > 0 ? 1 : -1), 0.2]);
\color{blue}{M_NUMBER} on arvteljel \color{green}{M_WHOLE}st \color{green}{fraction(M_NUMERATOR, DENOMINATOR)} võrra paremalvasakul.
style({ stroke: GREEN, fill: "#6495ED", strokeWidth: 3.5, arrows: "->" });
line( [ M_WHOLE, 0 ], [ SOLUTION, 0 ] );

label( [ SOLUTION, -0.83 ], NUMBER, "center", { color: "#FFA500" });

Oranž number näitabki murru \color{orange}{NUMBER} asukohta arvteljel.
