You will first take 6.5*10000=650000
then 2.5*100=2500
actor that u subtract 650000-2500=647500
The answer is 10x10x10=1,000
ten times ten times ten is one thousand
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!
