Step-by-step explanation:

All you're doing is × or   ×

-

×

so 5 × 16 = 80

and

8 × 1 = 8

The fraction becomes

then you simplify ( in this case divide by the botton number/denominator) to get :

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl

the answer is two. hope this !
