Answer:
See explanation
Step-by-step explanation:
Let
be the coordinates of the point which has to be dilated with the scale factor of
with the center of dilation at point
(the origin).
The dilation with the scale factor
and the center of dilation at the origin has the rule

So, you have simply to multiply each coordinate of the point by
to get the image's coordinates.

Step-by-step explanation:
We have

To simplify it we can divide numerator and denumerator by the same number (the greatest possible is the best)

- its the simples form..
6.2 is not a whole number
150/3 = 50 = a whole number
25 and 13 are whole numbers.
((800+100+400+35)÷3,250)×100
