18:24 = 3/4
4:70 = 2/35
35:105 = 1/3
22:7 = 22/7
12:165 = 4/55
The answer is equal the lengths change when a shape is dilated but the ratio of it does not
33.3% is the answer, I think
20/60 ---> 1/3, covert this to a percentage and it equals 33.3%
On dividing all the three ratios with 2 u can simplify it as
2:11:15
Hope it helps.
Dont forget to say thx if it helps
