Marty has saved $72. He spent $8 on a video rental. Write a ratio as a fraction in simplest form to represent what portion of his savings he has left.
a)64/72
b)8/72
c)1/9
d)8/9

D) 8/9

Step-by-step explanation:

You subtract 8 from 72 to get 64 which is the amount he had left so it would equal 64/72 but it asks for simplest form so you find the greatest common denominator which is 8 to get 8/9

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

part d
