<span>First we,Find the other side of the bed!

Which would be 60 since 4800/80(the other side) would give us 60

now we take 80 and divide it by 12 ( since the dimension is 1/12) to get 6.667

now we do the same for the 60 ( the other side that we found above)
so 60/12 would equal 5

 So now we multiply the two new found numbers (5 and 6.6667)
 5 * 6 = 30

So your answer would be 30 Inches squared.... I hope that this helps you!!
 I got 20 by 20 equals 400 inches squared so the sides would be 20 message me for more!

Divid to get the other side :) so if the doll house is 1/12 of the queen size bed you divid each side by 12 see. 4800/80=60. 80/12=6.6667.... so 60/12=5. so then 5x6 1/3. hope this helps you ... goood luck! :)

Answer:

Elizabeth had 30 stamps originally.

Step-by-step explanation:

Let,

x be the number of stamps Elizabeth have.

Number of stamps given to John = 1/6 of x = \frac{1}{6}x

Remaining stamps = x-\frac{1}{6}x = \frac{6x-1x}{6} = \frac{5}{6}x

Stamps given to Peter = 1/5 of remainder = \frac{1}{5}*\frac{5}{6}x = \frac{1}{6}x

Number of stamps left = 20

Now,

\frac{1}{6}x + \frac{1}{6}x + 20 = x\\\\\frac{1x+1x+120}{6} = x\\\\\frac{2x+120}{6} = x\\\\2x + 120 = 6x \\\\120 = 6x - 2x \\\\120 = 4x \\4x = 120

Dividing both sides by 4

\frac{4x}{4}=\frac{120}{4}\\x=30

Hence,

Elizabeth had 30 stamps originally.
