A color(1) clothing(1) costs $NUM1, and a popular color(2) clothing(2) costs NUM2 times as much. How much does the color(2) clothing(2) cost? \$TOTAL

The cost of the color(2) clothing(2) is a multiple of the cost of the color(1) clothing(1), so find the product.

The product is NUM2 \times $NUM1. NUM2 \times$NUM1 = $TOTAL The color(2) clothing(2) costs$TOTAL.

A color(1) clothing(1) costs $TOTAL, which is NUM2 times as much as a color(2) clothing(2) costs. How much does the color(2) clothing(2) cost? \$NUM1

The cost of the color(1) clothing(1) is a multiple of the cost of the color(2) clothing(2), so find the result of dividing.

This result, called the quotient, is equal to $TOTAL \div NUM2.$TOTAL \div NUM2 = $NUM1 A color( 2 ) clothing( 2 ) costs$NUM1.

A color(1) clothing(1) costs $TOTAL, and a color(2) clothing(2) costs$NUM2.

The color( 1 ) clothing( 1 ) costs how many times as much as the color( 2 ) clothing( 2 ) costs?

NUM1

The cost of the color(1) clothing(1) is a multiple of the cost of the color(2) clothing(2), so find the result of dividing.

This result, called the quotient, is $TOTAL \div$NUM2.

$TOTAL \div$NUM2 = NUM1

The color( 1 ) clothing( 1 ) costs NUM1 times as much as the color( 2 ) clothing( 2 ) costs.

person(1) RODE his BIKE for NUM1 distance(1) on each of the past NUM2 days. person(1) RODE his BIKE for NUM1 plural_form(distance(1), NUM1) on each of the past NUM2 days.

person(1) RODE her BIKE for NUM1 distance(1) on each of the past NUM2 days. person(1) RODE her BIKE for NUM1 plural_form(distance(1), NUM1) on each of the past NUM2 days.

How many plural_form(distance(1)) did person(1) RIDE his BIKE altogether?

How many plural_form(distance(1)) did person(1) RIDE her BIKE altogether?

TOTAL plural( distance(1) )

The total number of plural_form(distance(1)) BIKED is the product of the number of plural_form(distance(1)) BIKED each day and the number of days that person(1) went BIKING.

The product is NUM1\text{ DISTANCE_PER_DAY} \times NUM2\text{ DAYS}.

NUM1\text{ DISTANCE_PER_DAY} \times NUM2\text{ DAYS}= TOTAL\text{ plural( distance(1) )}

person( 1 ) BIKED a total of TOTAL distance( 1 ).

person( 1 ) BIKED a total of TOTAL plural_form(distance( 1 ), TOTAL).

person(1) RODE his BIKE for a total of TOTAL distance(1) over the past NUM2 days, and he RODE the same amount each day. person(1) RODE his BIKE for a total of TOTAL plural_form(distance(1), TOTAL) over the past NUM2 days, and he RODE the same amount each day.

person(1) RODE her BIKE for a total of TOTAL distance(1) over the past NUM2 days, and she RODE the same amount each day. person(1) RODE her BIKE for a total of TOTAL plural_form(distance(1), TOTAL) over the past NUM2 days, and she RODE the same amount each day.

How many plural_form(distance(1)) did person(1) RIDE his BIKE each day?

How many plural_form(distance(1)) did person(1) RIDE her BIKE each day?

NUM1 plural( distance(1) )

The number of plural_form(distance(1)) BIKED each day is the total number of plural_form(distance(1)) BIKED divided by the number of days that person(1) went BIKING.

We are looking for the quotient, which is TOTAL\text{ plural_form(distance( 1, TOTAL ))} \div NUM2\text{ DAYS}.

TOTAL\text{ plural( distance( 1 ) )} \div NUM2\text{ DAYS} = NUM1 \text{ DISTANCE_PER_DAY}

person( 1 ) BIKED NUM1 plural_form(distance(1), NUM1) each day.

person(1) has BIKED his BIKE for a total of TOTAL distance(1) since he started BIKING daily.person(1) has BIKED his BIKE for a total of TOTAL plural_form(distance(1), TOTAL) since he started BIKING daily. He has been BIKING NUM2 distance(1) each day.He has been BIKING NUM2 plural_form(distance(1), NUM2) each day.

person(1) has BIKED her BIKE for a total of TOTAL distance(1) since she started BIKING daily.person(1) has BIKED her BIKE for a total of TOTAL plural_form(distance(1), TOTAL) since she started BIKING daily. She has been BIKING NUM2 distance(1) each day.She has been BIKING NUM2 plural_form(distance(1), NUM2) each day.

For how many days has person(1) been BIKING?

NUM1 days

The number of days that person(1) has been BIKING is the total number of plural_form(distance(1)) BIKED divided by the number of plural_form(distance(1)) BIKED each day.

TOTAL\text{ plural( distance( 1 ) )} \div NUM2\text{ DISTANCE_PER_DAY} = \text{DAYS_BIKING}

TOTAL\text{ plural( distance( 1 ) )} \div NUM2\text{ DISTANCE_PER_DAY} = NUM1\text{ DAYS}

person(1) is a farmer(1). He plants NUM1 row of plural_form(crop(1)) in a field(1).He plants NUM1 rows of plural_form(crop(1)) in a field(1). Each row has NUM2 crop(1).Each row has NUM2 plural_form(crop(1), NUM2).

person(1) is a farmer(1). She plants NUM1 row of plural_form(crop(1)) in a field(1).She plants NUM1 rows of plural_form(crop(1)) in a field(1). Each row has NUM2 crop(1).Each row has NUM2 plural_form(crop(1), NUM2).

How many plural_form(crop(1)) did person(1) plant in the field(1)?

TOTAL plural( crop(1) )

The number of plural_form(crop(1)) that person(1) planted is the product of the number of rows that he planted and the number of plural_form(crop(1)) planted in each row.

The number of plural_form(crop(1)) that person(1) planted is the product of the number of rows that she planted and the number of plural_form(crop(1)) planted in each row.

The product is NUM1\text{ ROWS_OF_CROPS} \times NUM2\text{ CROPS_PER_ROW}.

NUM1\text{ ROWS_OF_CROPS} \times NUM2\text{ CROPS_PER_ROW} = TOTAL plural( crop(1) )

He plants a total of TOTAL crop(1) in the field(1).He plants a total of TOTAL plural_form(crop(1), TOTAL) in the field(1).

person(1) is a farmer(1). She plants NUM1 row of plural_form(crop(1)) in a field(1).She plants NUM1 rows of plural_form(crop(1)) in a field(1). Each row has the same number of plural_form(crop(1)). She plants a total of TOTAL crop(1) in the field(1).She plants a total of TOTAL plural_form(crop(1), TOTAL) in the field(1).

How many plural_form(crop(1)) did person(1) plant in each row?

NUM2 plural( crop(1) )

The number of plural_form(crop(1)) that person(1) planted in each row is the total number of plural_form(crop(1)) that he planted divided by the number of rows.

The number of plural_form(crop(1)) that person(1) planted in each row is the total number of plural_form(crop(1)) that she planted divided by the number of rows.

The result, called the quotient, is TOTAL\text{ plural_form(crop( 1 ), TOTAL)} \div NUM1\text{ ROWS_OF_CROPS}.

TOTAL\text{ plural( crop( 1 ) )} \div NUM1\text{ ROWS_OF_CROPS} = NUM2\text{ CROPS_PER_ROW}

How many rows of plural_form(crop(1)) did person(1) plant in the field(1)?

NUM2 plural( 'row' )

The number of rows of plural_form(crop(1)) that person(1) planted is the total number of plural_form(crop(1)) that he planted divided by the number of plural_form(crop(1)) in each row.

The number of rows of plural_form(crop(1)) that person(1) planted is the total number of plural_form(crop(1)) that she planted divided by the number of plural_form(crop(1)) in each row.
