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
