Which of the following is the similitary ratio from the smaller rectangle to the larger rectangle

2/3

Step-by-step explanation:

When looking at those two similar rectangles, we know the smaller one went through a dilation process to make the larger one.  We just have to find the ratio that links the smaller one to the larger one.

That's easy... just compare the ratio of the dimension we have:

10/15, which can be simplified at 2/3, which is one of the possible answers.

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
