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.
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.
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.
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.
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" ).

person( 1 ) invited INVITEES friends to his( 1 ) birthday party. Some people had other plans and could not attend, but N/D of the people person( 1 ) invited were able to attend.
How many people went to person( 1 )’s birthday party?
We can multiply \dfrac{N}{D}
by INVITEES
to find out how many people attended the party.
\color{#e00}{\dfrac{N}{D}} \cdot INVITEES
\color{#e00}{\dfrac{N}{D}} \cdot INVITEES
\color{#e00}{\dfrac{N * INVITEES}{D}} = SOLUTION
After saving up for a while, person( 1 ) had $AMOUNT in his( 1 ) piggy bank, and he( 1 ) spent N/D of that money on books at the bookstore.
How much money did person( 1 ) spend?
Round to the nearest cent, or hundredth of a dollar.
We, we can multiply AMOUNT
by \dfrac{N}{D}
to find out how much money person( 1 ) spent.
\color{#e00}{\dfrac{N}{D}} \cdot AMOUNT
\color{#e00}{\dfrac{N * AMOUNT}{D}} = SOLUTION
person( 1 ) spent $SOLUTION on books.
Every day person( 1 ) put the extra change from his( 1 ) pockets into a glass jar. After randRange( 10, 30 ) weeks, person( 1 ) had saved up $AMOUNT. person( 1 ) decided to use N/D of the money from the jar to buy canned food for a homeless shelter.
How much money did person( 1 ) spend on canned food?
Round to the nearest cent, or hundredth of a dollar.
We can multiply AMOUNT
by \dfrac{N}{D}
to find out how much money person( 1 ) spent on canned food.
\color{#e00}{\dfrac{N}{D}} \cdot AMOUNT
\color{#e00}{\dfrac{N * AMOUNT}{D}} = SOLUTION
person( 1 ) spent $SOLUTION on canned food for the homeless shelter.
Before leaving on a road trip, person( 1 ) filled up his( 1 ) gas tank, which holds GALLONS gallons of gas. After 0.5 * randRange( 3 / 0.5, 10 / 0.5 ) hours, person( 1 ) noticed that the gas tank was N/D full.
How many gallons of gas were left in the tank?
Since a fraction of the gas in his( 1 ) tank was left, we can multiply GALLONS
by \dfrac{N}{D}
to find out how much gas was left in the tank.
\color{#e00}{\dfrac{N}{D}} \cdot GALLONS
\color{#e00}{\dfrac{N * GALLONS}{D}} = SOLUTION
person( 1 ) had SOLUTION gallons of gas left in his( 1 ) tank when he( 1 ) checked.
ATTENDEES people had a picnic in the park. N/D of the people at the picnic were adults.
How many adults were at the picnic?
We can multiply ATTENDEES
by \dfrac{N}{D}
to find out how many people at the picnic were adults.
\color{#e00}{\dfrac{N}{D}} \cdot ATTENDEES
\color{#e00}{\dfrac{N * ATTENDEES}{D}} = SOLUTION
SOLUTION people at the picnic were adults.
