randRange( 1, 5 ) randRange( 1, 5 ) randRange( 1, 5 ) A + B + LEFT

person( 1 ) ate plural( A, "slice" ) of pizza( 1 ), and person( 2 ) ate plural( B, "slice" ).

If there were initially TOTAL slices, what fraction of the pizza( 1 ) was eaten?

(A + B) / TOTAL

\text{fraction of pizza( 1 ) eaten} = \dfrac{\text{number of slices eaten}}{\text{number slices total}}

They ate \color{#6495ED}{A + B} out of TOTAL slices.

init({ range: [ [-2, 2], [-2, 2] ], scale: 25 }); var eaten = A + B; piechart( [ eaten, TOTAL - eaten ], [ "#6495ED", "#FFA500" ], 2 );

They ate \dfrac{A + B}{TOTAL} of the pizza( 1 ).

person( 1 ) ate plural( A, "slice" ) of pizza( 1 ), and person( 2 ) ate plural( B, "slice" ).

If there were plural(LEFT, "slice") remaining, what fraction of the pizza( 1 ) was eaten?

(A + B) / TOTAL

\text{fraction of pizza( 1 ) eaten} = \dfrac{\text{number of slices eaten}}{\text{number slices total}}

Since they ate A + B slices of pizza( 1 ) with plural( LEFT, "slice" ) remaining, they must have begun with TOTAL slices.

They ate \color{#6495ED}{A + B} out of TOTAL slices.

init({ range: [ [-2, 2], [-2, 2] ], scale: 25 }); var eaten = A + B; piechart( [ eaten, TOTAL - eaten ], [ "#6495ED", "#FFA500" ], 2 );

They ate \dfrac{A + B}{TOTAL} of the pizza( 1 ).

person( 1 ) ate plural( A, "slice" ) of pizza( 1 ), and person( 2 ) ate plural( B, "slice" ).

If person( 1 ) ate \dfrac{A}{TOTAL} of the pizza( 1 ), what fraction of the pizza( 1 ) was eaten?

(A + B) / TOTAL

If plural( A, "slice") representA > 1 ? "" : "s" \dfrac{A}{TOTAL} of the pizza( 1 ), there must have been a total of TOTAL slices.

\text{fraction of pizza( 1 ) eaten} = \dfrac{\text{number of slices eaten}}{\text{number slices total}}

They ate \color{#6495ED}{A + B} out of TOTAL slices.

init({ range: [ [-2, 2], [-2, 2] ], scale: 25 }); var eaten = A + B; piechart( [ eaten, TOTAL - eaten ], [ "#6495ED", "#FFA500" ], 2 );

They ate \dfrac{A + B}{TOTAL} of the pizza( 1 ).

person( 1 ) ate plural( A, "slice" ) of pizza( 1 ), and person( 2 ) ate plural( B, "slice" ).

If there were initially TOTAL slices, what fraction of the pizza( 1 ) is remaining?

LEFT / TOTAL

\text{fraction of pizza( 1 ) remaining} = \dfrac{\text{number of slices remaining}}{\text{number slices total}}

Together they ate A + B slices, which leaves LEFT out of TOTAL slices remaining.

init({ range: [ [-2, 2], [-2, 2] ], scale: 25 }); var remaining = TOTAL - A - B; piechart( [ remaining, TOTAL - remaining ], [ "#FFA500", "#6495ED" ], 2 );

There is \dfrac{LEFT}{TOTAL} of the pizza( 1 ) remaining.

person( 1 ) ate plural( A, "slice" ) of pizza( 1 ), and person( 2 ) ate plural( B, "slice" ).

If person( 1 ) ate \dfrac{A}{TOTAL} of the pizza( 1 ), what fraction of the pizza( 1 ) is remaining?

LEFT / TOTAL

If plural( A, "slice" ) representA > 1 ? "" : "s" \dfrac{A}{TOTAL} of the pizza( 1 ), there must have been a total of TOTAL slices.

\text{fraction of pizza( 1 ) remaining} = \dfrac{\text{number of slices remaining}}{\text{number slices total}}

Together they ate A + B slices, which leaves LEFT out of TOTAL slices remaining.

init({ range: [ [-2, 2], [-2, 2] ], scale: 25 }); var remaining = TOTAL - A - B; piechart( [ remaining, TOTAL - remaining ], [ "#FFA500", "#6495ED" ], 2 );

There is \dfrac{LEFT}{TOTAL} of the pizza( 1 ) remaining.
