Question

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?

Answer 1

The dimensions of the model bed are A. 0.8 foot x 1.2 feet

Multiply the dimensions of Kelly's bed by the scale factor, $\frac{1}{5}$, to solve for the dimensions of the model bed.

4 x $\frac{1}{5}$ = 0.8 foot
6 x $\frac{1}{5}$ = 1.2 feet

So, the dimensions of the model bed are 0.8 foot x 1.2 feet.

Answer 2

Hey! 
So when there is a scale factor you would always multiply it with the original dimensions, even if it wasn't a fraction.
so 4 time 1/5 is 0.8
and 6 times 1/5 is 1.2
so the dimensions of the model bed is 0.8 foot by 1.2 feet
Your answer is A!
Hope this helps!
