Kaitlyn creates an architectural blueprint of a rectangular dining room.The area of the actual dining room is 900 times as large
8090 [49]
We need to make a scale between blueprint and actual size. The trick in this question is to understand that the scale for the areas and the scale for the lengths are different.
Scale for area is given in the question as
1 unit on blueprint = 900 units in actual.
As the dining room is given to be rectangular we can find the scale for lengths by taking square root of scale for area.

√1 unit on blueprint = √900 units in actual
Therefore, scale for length= 1:30

Thus, by using the scale we can calculate actual length corresponding to 4 inches on blueprint by multiplying 4 with scale
4 inches×1/30=120inches

Answer = 120 inches

Answer:

0.46=\frac{23}{50}

Step-by-step explanation:

To write any decimal as a fraction you divide by 1 and multiply by a number (ranging from 10, 100, 1000 etc.) that will make 0.46 a whole number, this will explain:

Let x = \frac{0.46}{1}

10x = 10*\frac{0.46}{1} =\frac{4.6}{10}

100x = 100*\frac{0.46}{1}=\frac{46}{100} this is our perfect fraction, now we simplify later

100x - 10x = \frac{46}{100} -\frac{4.6}{10}

90x = \frac{46}{100} -\frac{4.6}{10} =0  this is to confirm both fractions are equal

x is the same as \frac{0.46}{1} as \frac{4.6}{10} as \frac{46}{100} but here x = \frac{46}{100} because a fraction has to have no decimals.

So  0.46 is equal any of these values, as a fraction, on the other hand, it's improperly equal to \frac{46}{100} = \frac{23}{50} here I divided by 2 to bring down the proper fraction. (fraction at its simplest form)
