Answer:
1/2
Step-by-step explanation:
dilation often means multiplying. it says "dilation of the larger triangle"
the larger triangle has a side of 6 units.
the smaller triangle has a side of 3 units.
if you multiply 6 by 0.5, you get 3.
even though the number gets smaller, you are still multiplying.
now, if it said "dilation of the smaller triangle," we'd have a different answer. in that case, we would have to divide 6 by 3 to get 2.
the answer is 1/2
