Answer:
One-fifth
Step-by-step explanation:
step 1
Find the distance between the origin and the point B
the formula to calculate the distance between two points is equal to

we have
O (0,0) and B(10, –15)
substitute


step 2
Find the distance between the origin and the point B'
the formula to calculate the distance between two points is equal to

we have
O (0,0) and B'(2,-3)
substitute


step 3
Find the scale factor of the dilation
The scale factor is equal to divide the length of segment OB' by the length of segment OB
so

so
