If DEF~ABC, what is the similarity ratio of DEF to ABC?

Using the dimensions of the bases
EF = 9
BC = 6
Ratio = 9/6 which reduces to 3/2
The answer would be A
Answer:
AB=43\times DE\\\text{ then:}\\ DE=\dfrac{AB}{43}=\dfrac{60}{43}
Step-by-step explanation:
Since the similarity ratio is 43, then:
AB=43\times DE\\\text{ then:}\\ DE=\dfrac{AB}{43}=\dfrac{60}{43}
