Move the orange dot to select your answer.

Because \color{orange}{NUMBER} is positive negative the orange dot will be to the right left of 0.

Let's convert the improper fraction \color{orange}{NUMBER} to a mixed number:

\color{orange}{NUMBER} = \color{blue}{M_NUMBER}

Therefore, we know \color{blue}{M_NUMBER} lies between \color{green}{M_WHOLE} and \color{green}{M_WHOLE + (SOLUTION > 0 ? 1 : -1)} on the number line.

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} is \color{green}{fraction(M_NUMERATOR, DENOMINATOR)} to the rightleft of \color{green}{M_WHOLE} on the number line.

style({ stroke: GREEN, fill: "#6495ED", strokeWidth: 3.5, arrows: "->" }); line( [ M_WHOLE, 0 ], [ SOLUTION, 0 ] ); graph.movablePoint.visibleShape.toFront(); style({ stroke: "#FFA500", strokeWidth: 3.5, arrows: "" }); 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]);
label( [ SOLUTION, -0.83 ], NUMBER, "center", { color: "#FFA500" }); graph.movablePoint.moveTo( SOLUTION, 0 );

The orange number shows where \color{orange}{NUMBER} is on the number line.
