Kelly was building a bed for her dollhouse. she used her bed, which is 4 feet × 6 feet, as a guide. she scaled down the dimensions of her bed by a factor 1 over 5. what are the dimensions of the model bed she built?

Dimensions of the model bed is 5 times shorter than a real bed.  That's mean

4/5  feet  x  6/5  feet

0.8 feet  x  1.2  feet

Best answer that i found on yahoo ok   set :   x= length of 2nd piece in cm  x- 3= length of 1st piece in cm  x-4= length of 3rd piece in cm  then since you know they all came from the 20 cm ribbon you add them together and set them equal to 20x+ x-3 +x-4 = 20  3x - 7= 20  3x= 27  x= 9  the shortest piece is the third piece which is x- 4  x-4  9-4 = 5  the length of the smallest piece is 5 cm.  the other lengths are  9 cm  6 cm
