By using 3/10 as a way of figuring out the answer to your question is the best and only way to complete this;).
So first you want to figure out what 1/2 of 60 is which is 30.
Then you will want to figure out what 1/5 is of 30 which is 6
So know you do the math 6 times 3 which is "18" your answer!!!!!!!

Hope this helps

Answer:

The triangle in the bottom left.

Explanation:

A scale factor of 3/10 will multiply the length of each side by 3/10.

The length of the side given in the original figure is 60 cm; this means the scale model will have a side equal to

60(3/10) = (60/1)(3/10) = (60*3)/(1*10) = 180/10 = 18 cm

The one that applies is in the bottom left.
