Tyra has 12 2/3 cups of sugar. If r is the amount of sugar called for in one batch of cookies,

the expression 12 2/3 ÷ r can be used to find how many batches Tyra can make with the sugar she has.

If r is 2/3 cup, how many batches of cookies can Tyra make?

__________________________________________

She has 12 2/3 cups

r (amount of sugar per batch)

Number of batches= cups of sugar/r

______________________________

Cups of sugar= 12 2/3 cups

r= 2/3 cup

12 2/3 ÷ 2 / 3

= (12*3 +2)/3 ÷ 2 / 3

= (36 +2)/3 ÷ 2 / 3

= (38)/3÷ 2 / 3

= 38/3 * 3/2

= 38*3 / 3*2

= 38/2

= 19

_____________________________

Answer

Tyra can make 19 batches of cookies if r is 2/3
