Answer:

x=6 3/7

Step-by-step explanation:

Take the small side length of the big model and divide it by the large side length of the big model.

This would be 7/15.

Do this the same way for the small model.

Take the small side length and divide it by the longer length.

This would be 3/x

Set the two equations equal to each other.

3 = 7

x = 15

The scale factor is 2 1/3. This means that 2 1/3 times 3 equals 7. Divide 15 by the 2 1/3 to find x.

x will equal 6 3/7
