30 cm on the smaller figure corresponds to 12 meters on the larger figure.
We can write the ratio 30 cm : 12 m
If we divide both parts by the GCF 6 then,
30/6 = 5
12/6 = 2
This means the ratio 30 cm : 12 m reduces to 5 cm : 2 m
Telling us "2 meters on the real house correspond to 5 cm on the doll house"
Answer: Choice B. 5 cm : 2 m
