Tyra has 12 2/3 cups of sugar if r is the amount of sugar called for one batch of cookies the expression 12 2/3 divided by r can be used to find how many batches Tyra can make with sugar she has if r is 2/3 how many batches of cookies can Tyra make

a=r

d=q

c=p

b=s

hope this !

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
