Question

Kyra was building a bed for her dollhouse. She used her bed, which is 4 feet × 5 feet, as a guide. She scaled down the dimensions of her bed by a factor 1/5 . What are the dimensions of the model bed she built?

0.8 ft × 0.1 ft
0.4 ft × 0.5 ft
0.8 ft × 1 ft
0.04 ft × 0.05 ft

Answer 1

4(1/5) by 5(1/5)

4/5 by 1

0.8 ft by 1 ft

0.8 ft x 1 ft

Answer 2

The correct option is C.

Explanation:

According to the given information the initial dimensions of Kyra's bed are 4 feet × 5 feet.

The length of and width of the bed are 4 feet and 5 feet.

It is given that she scaled down the dimensions of her bed by a factor
`(1)/(5)` . It means the length and width of the new bed are
`(1)/(5)th` of initial bed.

`(1)/(5)* 4=(4)/(5)=0.8`

`(1)/(5)* 5=(5)/(5)=1`

The dimensions of the model bed she built are 0.8 ft × 1 ft, therefore option C is correct.
