For this case we have to:
x: Be the variable that represents the largest number
y: Be the variable that represents the smallest number
We propose a system of equations:
From the first equation we have to:
Substituting in the second equation:
We look for the value of "x":

Answer:
The two figures are similar and hey are not solid.
Step-by-step explanation:
I think your question is missed of key information, allow me to add in and hope it will fit the original one.
<em>Leah claims that these figures are not similar. When she compared the heights, she wrote 2/7. Then she compared the bases and 21/6. Why is Leah having trouble? Explain completely</em>
(Please have a look at the attached photo)
My answer:
In the first ratio, she compared the small figure's height to the large figure's height that is: 2/7
In the second ratio, she compared the large figure's base to the small figure's base that is: 21/6
=> She is wrong in this step, the ratio must be 6/21
Hence she needs to compare bases and heights thorugh division because the ratio between heights and the ratio between bases must be equal
The scales are equal
=> Therefore, those rectangles are congruent.
