Pls answer question asap. And i'll give brainliest.

least is box #2, then box #1, then box #3

Step-by-step explanation:

Least:  3/4 x 4/9 = 3/9  → 9/27

7/7 x 4/9 = 1 x 4/9 = 4/9  → 12/27

5/3 x 4/9 = 20/27

Greatest:  2 x 4/9 = 8/9  → 24/27

when you have a common denominator, in this case it's 27, then compare numerators

ca = ec

cpctc makes it so that corresponding parts of the triangle you proved to be equal are equal, the other options aren't part of the part of the triangles you proved to be equal.
