Order the following fractions from least to greatest:
SORTER.init( "sortable" )
SORTER.getContent()
if (SORTER.hasAttempted) {
return guess.join(",") === FRACTION_SORT_TEX;
} else {
return "";
}
SORTER.setContent( guess );
Let's change the fractions to have a common denominator of LCD:
\qquad
\NUM[4]{NUM[3]} \times
\dfrac{LCD / NUM[2]}{LCD / NUM[2]} =
\NUM[4]{\dfrac{NUMS_LCD[I]}{LCD}}
Now that our fractions have the same denominator, we can order their numerators from least to greatest:
\qquad NUMS_SORT_COLOR
The fractions listed in order from least to greatest are as follows:
\qquad FRACTION_LCD_SORT_COLOR.
Finally, let's convert the fractions back to their original form:
\qquad NUMS_SORT_TEX_COLOR.
