I'm in 5th grade and here's my question:
I have to write which fraction represents the ratio of corresponding sides? There are 2 triangles. One triangle has the measurements 3in., 9in. and 6in. The other triangle is 18in., 54in. and 36in.
Thank you.

3x0

the sides of the larger are in the ratio 18/3 = 54/9 = 36/6
That ratio is 6:1 or 6/1
if you compare the smaller to the larger, that would be 1/6

3:18 9:54 and 6:36
Notice how you have to multiply the first number by 6 to get the second number.
Hope this helps!

That's easy 3:18
9:54
6:36
3*6:18
9*6:54
6*6:36
So the ratio of them is 6/1 or 6
