We need to find out how many gallons will fill the whole tank
we first write 3/4 into its decimal fraction. 3/4 = 0.75.
Now we form an equation
0.75 = 12
1 = x (where x is he number of gallons needed to fill whole tank)
Simplify the equation:
0.75 × x = 12 × 1
0.75x = 12
x = 12 / 0.75
x = 16
It will take 16 gallons to fill whole tank to capacity.
Half gallon bottles that can be filled from the tank are:16 x 2 = 32
So 32 half gallon bottles can be filled from the full tank.
A transformation of a figure in which all of the dimensions of the figure are multiplied by the same scale factor is called a dilation.
Effect of Dilation on Perimeter
Whenever a figure is dilated by a scale factor, the perimeter of the figure changes according to the same scale factor.
Effect of Dilation on Area
When a figure is dilated by a scale factor of , the area of the figure is dilated by a scale factor of
Example-
Lets imagine a rectangle with length 10 cm and width 8 cm
So area becomes = 10*8 = 80 square cm
Lets suppose the rectangle is reduced by a scale factor of to produce a new rectangle.
So we will find the square of scale factor =
Now to find the area of the new rectangle(dilated one) we will multiply the area of the original rectangle by 1/4
=
Hence, area becomes 20 square cm.
