Let
....(1)
Multiply both sides of equation (1) by 10.
.... (2)
Multiply both sides of equation (1) by 100.
... (3)
Subtract equation (2) from equation (3)



Hence, the required fraction form is
.... Answer.
Answer:
You can calculate the area of the circle
We know the formula is: 
And if diammeter is 800, then the radio is a half: 400
We replace:
feet
So now we can divide:
502654/1000 = 502,654 minutes
Actually, its not 4b + 5r its 4b +3r because look
step 1. 6b + 4r - (2b + r)
step 2. 6b + 4r - 2b - r
step 3. (6b - 26) + (4r - r)
step 4. 4b + 3r
So the answer is actually 4b + 3r

For this case we have the following data:
The original dimensions of the drawing are:
If the copier zoom is at 120%, we can find the new dimensions of the drawing by making a rule of three:
Width:
3 ----------> 100%
x ----------> 120%
Where x represents the new width of the drawing:

Long:
5 ----------> 100%
y ----------> 120%
Where y represents the new long of the drawing:

Thus, the new dimensions are 3.6 cm wide and 6 cm long
Answer:
the longer dimension of the new drawing is 6cm
