Triangle I has sides with lengths 2 2/3 cm, 4 1/2 cm and 3 cm. Triangle II has sides with lengths 8 cm, 13 1/2 cm and 9 cm. Are these triangles similar? If yes, what is the ratio of correspondence?
A.)Yes;1/3
B.)No
C.)Yes;2/3

(8/3) / 8 = 8/3 * 1/8 = 8/24 = 1/3.
(9/2) / (27/2) = 9/2 * 2/27 = 18/54=1/3.
3 / 9 = 1/3.
